Ok, it's getting late and I've been here for 12 hours, so here is something crazy and I'm not sure if it's even real, but wow if it is.

Highest winds and heaviest rains will continue to affect the I-95 cooridor and east in and around D.C. Flash Flood Warnings continue to 3:15am for Anne Arunel, Baltimore County and City. 

11:25pm Update:

Flash Flood Warnings continue through 2:30am for D.C., Fairfax, Prince William, Arlington, Prince Georges, Montgomery and Howard Counties.

11:14pm Update:

Here is part of the latest forecast discussion for Irene, "MORE SO THAN WITH MOST STORMS...THE WINDS WITH IRENE INCREASE
SHARPLY WITH HEIGHT ABOVE THE SURFACE. AS IRENE MOVES THROUGH AREAS WITH HIGH-RISE STRUCTURES...THESE BUILDINGS COULD EXPERIENCE WINDS SIGNIFICANTLY STRONGER THAN THE SURFACE WINDS. WINDS AT THE 30-STORY LEVEL WILL LIKELY BE 20 PERCENT HIGHER THAN AT THE SURFACE...AND WINDS 80-100 STORIES UP COULD BE ABOUT 30 PERCENT HIGHER THAN AT THE SURFACE."

11:02pm Update:

The new public advisory is out for Hurricane Irene which is still a Category 1 storm with winds to 80 m.p.h. as it moves NNE at 16 m.p.h. 

10:56pm Update:

The Flash Flood Warning has been extended until 2am for Charles, Calvert, St. Mary's, Prince Georges and Anne Arunel Counties in MD. Very heavy rain will continue to fall over the next couple of hours.

10:49pm Update:

Life cycle of Irene over the past week:

10:41pm Update:

Parts of St. Mary's county have received over 8 inches of rain through the storm and winds appear like they are only reaching Tropical Storm force along the Bay. Wind gusts across the area are still on the order of 30 to 40 m.p.h. and will continue to be very gusty through the next 5 hours or so. Even with the hurricane to the north, the Outer Banks are still getting wind gusts from 50 to 60 m.p.h. Thomas Point Light just had a wind gust to 64 m.p.h.

9:33pm Update:

As of the 9pm update of Irene, winds are still at 80 m.p.h. moving NNE at 16 m.p.h. The pressure is at 951mb and the track keeps it as a hurricane as it passes just to the east of Ocean City late tonight.

Current Doppler Radar imagery is showing very heavy rainfall from D.C. to points east including most of Prince Georges, Charles, Anne Arundel and Calvert Counties. A bit of a break is beginning to come in to St. Mary's with another band farther south over the bay. In this heavy rain, high winds have been getting mixed down to the surface and numerous reports of 45+ m.p.h. wind gusts are coming in across our WeatherBug Network.

Flooding will still be the main concern tonight so be sure not to go out during the overnight hours unless you absolutely have to.

8:43pm Update:

A Flash Flood Warning remains in effect for the majority of the D.C. Metro area until 11:30pm tonight. There have been reports of over 5 inches of rain in parts of Southern Maryland with another 2 to 3 possible in the next few hours. A Flood Warning is also in effect until 12:30am for Calvert and St. Mary's counties where another half an inch or more is continuing to fall each hour.

8:21pm Update:

Reading some tweets I heard about a possible tornado 2 miles southwest of Lewes, DE on the eastern shore from Jim Cantore and also heard from our own Meteorologist Devon Lucie that about 70% of Richmond, VA has lost power. Be sure to follow me and the rest of the team on twitter for the latest updates and information on Irene.

8:03pm Update:

Our Interactive Radar is showing the next heavy band about to move into Anne Arundel and stretches down into Southern Maryland with winds sustained above 40 m.p.h. at Chesapeake Beach along the Bay. Expected Tropical Storm conditions over the next hour or so as this band moves through to the north and west.

7:44pm Update:

Saw Rob's comment below. We are not expecting much coastal flooding along the western side of the Bay as winds have been sustained out of the north and will gradually turn to the northwest as Irene's center moves north to the east of Ocean City. Also, the next high tide at Chesapeake Beach is 3:33am and Annapolis 4:55am which would put high tide after Irene has passed to the north. This will also help keep the water from piling up on the western shores of the Bay was winds will be out of the northwest.

7:00pm Update:

Rainfall totals... Leonardtown 4.57",  Ocean City 2.76",  Annapolis 2.54",  Oxon Hill 2.57",  Spotsylvania 2.38",  Waldorf 2.36",  D.C. 2.3",  Alexandria 2.16".

Also, check here for some of the latest wind gusts and rainfall totals from other locations around the D.C. area.

6:16pm Update:

The heaviest rains are beginning to fall all across the D.C. area with the highest potential for flooding along and east of I-95. We think 4 to 8 inches of rain will be possible. Be sure to check Live Doppler Radar for the latest positioning of the rain.

Also, please send any pictures or videos to iwitness@wjla.com and we will get them on air through the night.

5:29pm Update:

A Flash Flood Warning is in effect until 11:30pm tonight for portions of Howard and Montgomery in MD, Fairfax and Prince William in VA, and D.C. An additional 3 to 6 inches of rain will be possible with locally higher amounts.

5:17pm Update:

A Flash Flood Warning is in effect until 11pm tonight for Anne Arundel, Prince Georges and Charles Counties. An additional 4 to 8 inches of rain is possible in those areas through the overnight hours, which I think is absolutely possible. Flooding will be the primary threat through the night with the additional threat of downed trees. Remember, flooding is the number one weather-related cause of death in the United States.

5:04pm Update:

A Flash Flood Warning is in effect until 11pm tonight for Stafford, Spotsylvania and King George Counties. An additional 1-3 inches of rain is possible through the remainder of the night with locally higher amounts appearing likely. I really think there will be some spots over 6 inches of rain by the time this system is leaving tomorrow morning. Flooding appears like it will be a huge problem along and east of I-95 and trees will easily come down with saturated grounds and winds gusting from 40 to 50 m.p.h.

4:57pm Update:

Irene continues at hurricane strength with winds at 80 m.p.h. and gusts to 100 m.p.h. It is moving to the NNE at 13 m.p.h. and is still expected to move parallel to the coast of the Eastern Shore.

4:13pm Update:

The Tornado Watch continues for the Eastern Shore of Maryland until 8pm, but Calvert and St. Mary's counties in Southern Maryland have been dropped.

3:47pm Update:

Check here for the latest storm reports in the D.C. area. Numerous reports of flooding and trees down are coming in from Southern Maryland. Heavy rain and high winds will continue to make conditions worse through the remainder of the afternoon and into tonight. 

3:35pm Update:

The heaviest rain band is currently over Calvert and St. Mary's counties in Southern Maryland and will move very slowly to the north and west as the hurricane moves to the north. Rainfall rates should be around 0.5-1.0" per hour through the evening and overnight as Irene continues to move north.

Here is a great site to check out rainfall totals, winds, wind gusts, etc.

Here is a site that is showing streaming video from a guy that is chasing the storm in Rehoboth Beach, DE.

3:05pm Update:

A 62 m.p.h. wind gust has been reported at the Chesapeake Beach, MD station on our WeatherBug Network. They are reporting 40 m.p.h. sustained winds there. Also, Rehoboth Beach, DE has recorded a 56 m.p.h wind gust and Patuxent River NAS has recorded a 42 m.p.h. wind gust.

For rainfall totals so far, Leonardtown, MD has received 2.01" and Brandywind, MD 1.53". Expect A LOT more in the way of rain, as numerous locations in southern Virginia and northeastern North Carolina have recorded upwards of 8 inches.

2:42pm Update:

The eye wall is about to move into the Albermarle Sound in N.C. The eastern part of the eye wall which is the worst with the highest winds will be moving into Kill Devil Hills, NC and Nags Head, NC and eventually northern portions of the Outer Banks like Duck and Corrola.

2:31pm Update:

At 2pm, the National Hurricane Center's update shows Irene still as a Category 1 hurricane with winds of 85 m.p.h., gusting to 100 m.p.h. It is moving to the NNE at 13 m.p.h. and is expected to move right along the eastern shore this evening and tonight. 

2:03pm Update:

Rain continues to mainly affect areas along and east of the I-95 cooridor and a very large rain sheild exists all the way down to southern Virginia and North Carolina. In, N.C., 5 to 10 inches of rain has fallen with locally more in eastern portions of the state including New Bern and Beaufort where over 10 inches have been reported.

Local high tides may bring bigger issues with storm surge flooding possible, particularly overnight. Chesapeake Beach has high tides at 3:03pm today and 3:33am tomorrow. Annapolis has high tides at 4:25pm tonight and 4:55am tomorrow. Alexandria has high tides at 7:48pm and the next not until 8:05am which will not be a problem.

1:37pm Update:

Rainfall for the month has been heavy at Reagan National at 5.09" (+2.6" for August). It has been under at BWI Marshall and Dulles though with only 2.66" and 2.33" respectively at each airport. This will help bust the moderate drought conditions in our region.

1:23pm Update:

Based on Irene's latest location and movement, count on periods of heavy rain and high winds through at least the next 8 hours. The worst of the storm should be around Midnight as its center moves just east of Ocean City, MD.

1:17pm Update:

A Flash Flood Warning is in effect until 6:45pm for Calvert and St. Mary's counties in Southern Maryland. Our WeatherBug Network has seen 1.5 inches of rain in Leonardtown and 1.21 inches of rain in Huntingtown already.

The intense rainbands are beginning to move into the D.C. area and will continue to move in from the south through the afternoon and into the early overnight hours. In the heaviest rain bands, winds will pick up from northeasterly to easterly later this evening and tonight.

Here are the Virginia Surface Observations.
