Tropical Info. & Web Links
posted by Chris Naille: Meteorologist


So far the 2009 Atlantic Hurricane Season has been pretty quiet with only one tropical depression officially in the books. But, hey we still have a long way to go.  With our local weather pretty quiet this week and nothing currently brewing in the tropics I thought that I would take a few minutes to pass along some of my favorite web sites and some information that I think you may find helpful.

The graph below shows that the main peak of hurricane season is September 10th but also notice that there is a secondary peak that occurs in late October.

One common question that I hear often is..." where are storms most likely to form?"  This actually changes over the course of the season.  The illustration below identifies these hot spots and breaks them down from month to month. 

Saffir-Simpson Hurricane Scale

Category Winds Effects
One 74-95 mph No real damage to building structures. Damage primarly to unanchored mobile homes, shrubbery, and trees. Also, some coastal road flooding and minor pier damage
Two 96-110 mph Some roofing material, door, and window damage to buildings. Considerable damage to vegetation, mobile homes, and piers. Coastal and low-lying escape routes flood 2-4 hours before arrival of center. Small craft in unprotected anchorages break moorings.
Three 111-130 mph Some structural damage to small residences and utility buildings with a minor amount of curtainwall failures. Mobile homes are destroyed. Flooding near the coast destroys smaller structures with larger structures damaged by floating debris. Terrain continuously lower than 5 feet ASL may be flooded inland 8 miles or more.
Four 131-155 mph More extensive curtainwall failures with some complete roof strucutre failure on small residences. Major erosion of beach. Major damage to lower floors of structures near the shore. Terrain continuously lower than 10 feet ASL may be flooded requiring massive evacuation of residential areas inland as far as 6 miles.
Five greater than 155 mph Complete roof failure on many residences and industrial buildings. Some complete building failures with small utility buildings blown over or away. Major damage to lower floors of all structures located less than 15 feet ASL and within 500 yards of the shoreline. Massive evacuation of residential areas on low ground within 5 to 10 miles of the shoreline may be required.

2009 STORM NAMES:  Ana, Bill, Claudette, Danny, Erika, Fred, Grace, Henri, Ida, Joaquin, Kate, Larry, Mindy, Nicholas, Odette, Peter, Rose, Sam, Teresa, Victor,Wanda
