Many of us remember enduring days - some weeks - without power. Flooding and downed trees and power lines were just some of the hardships faced after Isabel slammed into the East Coast on Sept. 18, 2004.

NOAA

Hurricane Isabel has gone into the record books as one of the most significant tropical cyclones to affect the Chesapeake Bay area since Hurricane Hazel in 1954 and the Chesapeake-Potomac hurricane of 1933.  Here are a images of Isabel's impact in our area.

Isabel was the ninth named storm of the 2003 Atlantic hurricane season. It originated about 625 miles west of the Cape Verde Islands on Sept. 6, 2003. The storm tracked westward, gaining intensity and, at one point, reached Category 5 status with maximum estimated sustained winds around 165 mph. Check out Isabel's track:

NOAA

By the time Isabel made landfall near Drum Point, N.C. around midday Sept. 18, it was still a Category 2 hurricane with maximum sustained winds of 105 mph.

Isabel then tracked north-northwest, losing tropical characteristics, but still producing flooding rain and tropical storm force winds. Here's an image of the radar, as the center of Isabel tracked over North Carolina.

The copious amounts of rain, coupled with strong winds, tore down trees and power lines and even led to a few fatalities.

Locally, the Shenandoah Valley received 6-12 inches of rain. Between two and six inches of rain fell in western Maryland and eastern West Virginia, and the Baltimore/Washington region received a total of one to three inches of rain.

At the height of the storm, Reagan National recorded a wind gust of 50 mph.

Unusually high storm surge accompanied the storm with some watersheds between six and feet above normal. The storm surge in the Chesapeake Bay and Potomac River reached the highest levels since the Chesapeake/Potomac hurricane of 1933.

From emergency management reports, estimates of about 6 million customers lost power at some point during the storm in North Carolina, Virginia, Delaware, West Virginia, Pennsylvania, and Washington, D.C.

The estimated total economic loss from Isabel was about $5 billion, according to the American Reinsurance Group. With so many people affected by the tropical cyclone, it took a long while to fully recover.

Even with the advanced warning of the hurricane, thousands of people were impacted by Isabel.

Further information about Isabel is available from the National Hurricane Center, National Centers for Environmental Prediction, United States Geological Survey and the National Weather Service.

Fall Foliage 2013 in the Washington D.C. area

Email us your photos so we can share them! yourphotos@wjla.com

Please let us know your name and where the picture was taken. Thanks!

If you have already been seeing some color peeking out in recent weeks, you're not alone. Fall colors really begin to show in the month of October, with the peak occurring as soon as early October in the Mountains, and mid to late October closer to the D.C. Metro area. Two pictures below already show the big difference in color between the local area (Vienna, Westwood CC - Middle Picture) and the Northeast (New Hampshire - Bottom Picture).

Average Peak Fall Color in D.C.

The reason leaves change color is because of the colder days and approaching winter. As daylight gets shorter and temperatures start to drop, the leaves recoup nutrients, such as nitrogen and phosphorous. It's the chlorophyll in the leaves that give them their green color through the growing season. Chlorophyll is an essential compound for photosynthesis, which is a process that converts sunlight to carbohydrates.

Be sure to check all of our HD cams often over the next few weeks!

Taken by James Joslyn in Vienna at Westwood Country Club

Leaves are also made up of carotenoids. Carotenoids produce yellow, brown, and orange colors. They are always present in the leaves, but you only start to see them when the chlorophyll process stops. The chlorophyll process stops when temperatures start to drop, which is when the carotenoid colors are revealed.

Taken by Erik Ruediger at the Edward MacDowell Reservoir in New Hampshire

Wondering where the red and purple hues come from? These colors are the anthocyanins, which are a bit less understood by tree scientists. Some scientists are suggesting, though, that because of the moderate drought there are increased concentrations of these anthocyanins in the leaves, which will lead to some very vibrant hues of reds and purples in the leaves.

Want to learn how to photograph fall foliage? Here is a great blog by the Digital Photography School on exactly what you need to do.

Sunrise Special -- September Style!

September 25, 2013 - 09:48 AM
0 Comments

Looking at the early morning satellite, I had a feeling we'd be in for a colorful sunrise.  A disturbance off to the south had ushered in some mid and high level clouds.  It was a perfect recipe for a brilliant sunrise. 

Steve Chenevey - Washington, D.C.

To see all the colors of the rainbow, watch the video time lapse below.  Notice how quickly the colors change, as the sun angle gets higher.

The reason we enjoy such colorful sunrises is because the sunlight scatters through the lowest layer of the atmosphere. 

During sunrise and sunset, sunlight has to take a longer path through the atmosphere due to the low sun angle.  During this process, molecules scatter the blue and violet light away from our eyes revealing many other colors of the rainbow. 

When mid and high clouds are added to the mix, the sunlight is scattered and reflected more, which aids in the deep red and orange hues visible during these times. 

Since the sun angle is much lower in the fall and winter, sunrises and sunsets are even more brilliant.  This morning was a perfect example of everything coming together.  Check out these incredible images taken by our StormWatch7 Facebook and Twitter friends.  Thanks to everyone for sharing!

Dwindling daylight in D.C.

September 24, 2013 - 03:30 AM
0 Comments

It's that time of year when you notice the sun rising later and later, and before you know it, you'll need your headlights on at 6pm. Here's a brief breakdown of the amount of daylight in Washington and how much it's changing.

Today in Washington there is 12hr 4min of daylight, but we lose 1hr and 14min over the next 30 days alone. Basically, we add two and a half minutes of darkness every day between now and October 24th. Thursday (the 26th) will be the first time D.C. has had under 12 hours of daylight since March 16th. See the chart here.

Our daylight hits rock bottom around the winter solstice with only 9hr 26min of daylight then. It may feel dark that time of year, but it's nothing like Anchorage, Alaska where they have an annual low of only 5hr 28min of daylight.

Monday had the coolest high temperature in D.C. since May 25th

September 23, 2013 - 05:34 PM
0 Comments

Temperatures Monday reached 69°F at Reagan National Airport. This is the coolest the high temperature has been since May 25th earlier this year when it hit 68°F for the high. This isn't extremely cold, but is unseasonably cool with the average high now at 77°F.

Oddly enough, the last time low temperatures were in the 40s at Reagan National also occurred on May 25th, and there is an outside chance it could happen tomorrow morning, but at this time we think it will be closer to 50°F-53°F at Reagan National tomorrow morning.

This week actually features a very quiet weather pattern with one area of low pressure south of D.C. during the Wednesday-Thursday time period possibly bringing a few clouds, but no precipitation is expected through this weekend.

Even with the heavy rain this weekend that totaled around an inch in some areas, Reagan National is still down 1.5" for the month of September and 3" over the past two months as far as average precipitation is concerned.

D.C. Weather Turning Dry; Rain Needed

September 19, 2013 - 08:31 PM
0 Comments

The corn crop was remarkable this summer, the grass was luscious green but now lack of rain is starting to become a bit noticeable in the region.

As a matter of fact, the latest drought monitor, issued each week by the National Drought Mitigation Center, indicates the Washington area is abnormally dry. This designation precedes a moderate drought.

Latest Drought status

Notice how the abnormally dry designation matches well with the latest 60-day precipitation departures in the Mid-Atlantic. The DC area has seen the least amount of rain and thus has the highest rainfall deficit.

Latest Drought status

Looking back through monthly precipitation tallies, the rainfall deficit of 1.94 inches for September (so far) is the greatest deficit since November of last year. What has helped keep precipitation on target though for the year is the surplus seen in June; 6.19 inches above average. July was slightly above average for rain and August is when the dryness began. Rainfall was 1.59 inches below average. Note the precipitation departures in the graph below. Much of the year has been near average, with the significant spike in rainfall in June. However, the latest trends show less rain than average.

Latest Drought status

This is contributing to brown grass in spots and lower volume in area streams. The United States Geological Survey reports that a few streams in Maryland are running at 10% to 25% of their normal flow. Discharge is a great indicator of stream flow.

As for Washington, the Potomac River is still in great shape. Discharge is about 1,810 cubic feet per second at the USGS site near Little Falls. To put this in perspective, the lowest discharge recorded at this site is 121 cubic feet per second in September of 1966.

Latest Drought status

Ground water levels are still in fine shape but have been dropping at an accelerated rate since July. The nearest reporting site to Washington is in Dunkirk, Md., with water at about 43 feet below the ground. The record low is 49.19 feet set back in August of 2007. Given that groundwater levels fluctuate slowly, the dry pattern would have to continue for several more months to begin having problems with wells, etc.

Latest Drought status

The next threat for rain is Saturday, with potential of a half-inch as a cold front swiftly moves through the Mid-Atlantic. Beyond that, a dry weather pattern looks to take charge through much of next week.

Stay ABC7 for the latest on the weekend forecast and when you are away from your television, tune to WTOP for weather on the 8's.

Hurricane Humberto path: First hurricane of the season

September 11, 2013 - 10:40 AM
0 Comments
Photo: NOAA

We've had our fair share of tropical storms this 2013 Atlantic hurricane season, but up until this morning there had been no hurricanes. As of the 5am Wednesday (Sept.11th) update from the National Hurricane Center, Humberto strengthened into a hurricane in the far eastern Atlantic.

If Humberto had reached hurricane status tomorrow, it would have been the latest date for a hurricane to develop in the Atlantic.  Hurricane Gustav will remain the latest forming hurricane, since it developed on September 11th.  Wait, that's when Humberto formed, right?  Kind of, but not quite.  Gustav didn't reach hurricane status until the 8am update from the National Hurricane Center.  Humberto was named a hurricane at 5am from the NHC. 

As the graphic above states, it's important to note that even though these are the latest forming hurricanes, these years didn't all end in a slow hurricane season.  In fact, September of 2001 had a total of nine hurricanes. 

We are now just past the peak of hurricane season.  The Atlantic temperatures are warmest in the late summer and early fall, which is one of the main factors in hurricane development.

The two active tropical systems in the Atlantic (Tropical Storm Gabrielle) and Hurricane Humberto) both pose no immediate threat on the U.S.  Here's the latest track map for both storms. 

We'll continue to watch the tropics very closely over the next several months.  It was late October last year when hurricane Sandy slammed into the Northeast.

NASA Rocket Launch Tonight

September 6, 2013 - 11:00 AM
0 Comments

It's a big night at NASA Wallops.  A rocket launch is set for tonight, shortly before midnight.  NASA's Lunar Atmosphere and Dust Environment Explorer (LADEE) is a robotic mission that will "orbit the moon to gather detailed information about the atmosphere and composition of the thin lunar atmosphee and determine whether dust is being lofted into the lunar sky" NASA Wallops. 

NASA
NASA

The launch is scheduled for 11:27pm EDT Friday night (September 6th) from NASA Wallops Flight Facility in Wallops Island, VA.  Weather conditions for the launch look ideal.  Clear skies and light winds should aid in a successful launch (provided there are no other problems with the Minotaur V rocket that will launch LADEE, etc.). 

If you're hoping to catch a glimpse of the rocket after it takes off, you'll likely be able to see it in the eastern sky.  Check out this great image from NASA.  Within the red circle (about a 60 mile radius), people should see the rocket rise 10 seconds after launch time.  The rocket will be visible for folks in southern Maryland 30 seconds after the launch and for most of the WJLA viewing area the rocket will be seen two minutes after the launch.

 Here's a link to more information on the LADEE mission.

10 reasons D.C. weather is awesome

September 5, 2013 - 12:33 PM
0 Comments

1. The D.C. area gets all four seasons. Terrible cold (or sometimes mild) winters, beautiful spring and fall, and a nice hot and humid summer. We can deal with them as we know they only last 3 months each!

2. Uhh, sunrises and sunsets are unreal. I know this is true throughout the country, but they don't have the monuments now, do they? (AB Pan Photography)

3. Speaking of picturesque, fall foliage in the region can be spectacular. Anyone leaf peeping this fall?

Fall foliage rocks.

4. Severe weather can be bad, but it isn't nearly as bad as other areas of the country. There has never been an EF-5 tornado recorded east of the Appalachians, we've never had a category 5 hurricane, and even our earthquakes are weak (yea, geology included I guess).

OK, OK. The derecho was baaaad.

5. We have 14 hours and 54 minutes of daylight in the summer. Unless you work the graveyard shift, this is cool.

We get to wear really cool shades too.

6. The D.C. area sometimes gets blizzards that drop 2 feet of snow and close work down for a week. Though notoriously hard to forecast, once every couple of winters, these are awesome. Unless you get 3 in one winter like 2009-2010. We even have planned snowball fights!

7. October. It's arguably the best weather of the year every year, with sunshine, comfortable days and cool, crisp nights. Not to mention the foliage, pumpkins and fall brews!

We even had snow in late October a few years back!

8. Our "extreme" averages (oxymoron right there!) are 28°F for the average low in January and 89°F for the average high in July. Things could be MUCH worse.

And we can wear sweet hats!

9. D.C. gets all kinds of weather. From sunshine, to blizzards, severe weather, hurricanes, you name it. Talk about variety! No boredom here!

10. The D.C. area has 6 radars meteorologists can tap into! We, of course, have our own in Live Super Doppler 7 (shameless self-promotion), but also can tap into the Sterling radar as well as the terminal dopplers at Reagan, Dulles, BWI and Joint Base Andrews!

Here is a selection of the multiple radars we can use!

HIGH pollen counts in the D.C. area

September 4, 2013 - 11:57 AM
0 Comments

"We are right at the 'peak period' for our ragweed counts. To date, we have been below average for our daily ragweed counts. This is not much assurance, however, for ragweed sufferers in our area who are already wheezing and sneezing out there. Ragweed alone accounted for 41.53 grains/cubic meter or about 91% of the last 24 hour weed count total. Nettle family pollen, sage pollen and the chenopod/amaranth group (lambs qtrs and pigweed) also contribute to our weed count."

These are the words of our favorite Microbiologist, Susan Kosisky, who is the Director of Aerobiological Reporting and Evaluation at the US Army Centralized Allergen Extract Lab. She issues the Pollen Count for the D.C. area, which is HIGH not only for the weed count, but also for grasses and mold.

Wednesday's Pollen Count

Ragweed counts have been below average so far this season and were below average in August, but dry conditions have allowed it to come back early this September. With dry conditions expected the remainder of the week, ragweed should continue to be a problem to allergy sufferers across the region.

Ragweed

Tomorrow may be exceptionally bad for people allergic to ragweed, as a dry cold front will move through and breezy winds will allow for more of the pollen to be picked up into the air. Be sure to take the proper precautions and even though it will be nice out, keep your windows closed!

Other tips to beat your allergies:

-Take an over the counter antihistamine

-Change your clothes after being outdoors for a prolonged period of time

-Keep your windows closed in your vehicles and home

-Shower before bed to wash any pollen off your skin

-Try to stay inside between 10am and 4pm if possible as pollen counts are usually highest during that time period

September weather in Washington D.C.

September 2, 2013 - 05:14 AM
0 Comments

August went out with the high heat and humidity and September has continued with highs in the low 90s for the start of the month. So what should you expect for the remainder of the month? Here is a look at the average September conditions in the D.C. area.

Yesterday Reagan National reached 93 degrees, and is expected to do so once again today. This isn't completely out of the norm, as it hit 95 on September 1st last year, but the average high temperature for the start of the month is in the mid 80s (84°F), so the month will definitely start out above normal.

By September 30th, the average high is down to a comfortable 74°F, and average low temperatures are at 57°F! Reagan National hasn't been in the 50s since June 5th when it hit 59°F.

Record highs are in the 90s for the month but there are only three record highs at 100°F or better, so extreme heat is beginning to subside. Record lows really fall during the month from the 50s the beginning of the month to the upper 30s by the end.

Averages in September at DCA

One big thing you'll notice is the amount of daylight the area will lose during the month. September 1st starts with 13 hours and 1 minute of daylight, where as by the 30th, there will be under 12 hours of daylight at 11 hours and 49 minutes. The 26th is the first day this fall with under 12 hours of daylight.

Meteorological Fall started on the 1st of the month, but the Fall Equinox actually is on Sunday the 22nd this September at 4:44pm. This occurs when the sun lies directly over the equator. The tilt of the earth will begin to bring more direct sunlight to the Southern Hemisphere after the 22nd.

When do the leaves change around the D.C. area? Well you'll have to wait at least another month, as they won't change until closer to mid or late October.

Reminder, even though the tropics were quiet through August, the climatological peak in in September, so we'll be sure to keep you aware of anything that develops!
