Ladies and Gentlemen, welcome to hurricane season!

It's been a pretty slow season this year up until the last couple of days:
- Hurricane Humberto gained strength a couple days ago and is moving a little faster to the north into the southern mid-Atlantic as a Cat 1 with max sustained winds at 75 knots (~86 mph). Forecasts are showing that Humberto will be weakening over the next couple of days and will return back to a tropical storm late Friday night. For more information on Hurricane Humberto visit the National Hurricane Center's web site: http://www.nhc.noaa.gov/.

- Tropical Storm Gabrielle is taking center stage! The offshore waters of the Western Atlantic are under a Tropical Storm Warning! Tropical Storm Gabrielle is moving up the coast offshore and is taking it's time to stir up the Northwest Atlantic. There are currently no coastal watches or advisories but watercraft in the area should be careful. The center of Gabrielle was last located near [latitude 33.9 north, longitude 67.7 west] with max sustained winds at 35 knots (40 mph) extending outward up to 105 miles. She is moving north northeast at about 7 knots (8 mph) and will be speeding up and weakening over the next few days. For more information on Hurricane Humberto visit the National Hurricane Center's web site: http://www.nhc.noaa.gov/.


- May I also inform you that there is a 60% chance of a tropical cyclone developing in the Gulf of Mexico over the next couple of days. The upper level jet stream is way north near the great lakes so the air is relatively static near the Gulf. Only some 17-25 kt easterlies will be experienced in this region over the next couple of days allowing for moisture to gather in the atmosphere.

US Forecast

Raleigh is going to be experiencing some wonderful early fall weather this Saturday as the high is only supposed to reach the mid 70s. For the rest of Thursday into Thursday night there are possible isolated to widely scattered thunderstorms for the area.

Many of the New England States are under a severe thunderstorm watch right now and these could develop into warnings over the next 24 hours with the effects of Gabrielle and the Low Pressure System that is moving through.

Careful of flooding out in the West! Flash flood watches in effect for about 2/3 of the counties of New Mexico and much of Arizona, Nevada, Utah, Idaho, and Colorado as the front passes to the east.
