As Gabrielle departs, a new tropical wave in the central Atlantic is expected to strengthen into a tropical depression in the next few days. The next storm to develop would be called Humberto. The storm will move into the same warm waters as Dean and Felix did, which both blossomed into category 5 storms. We are also monitoring an area of disturbed weather in the western Gulf of Mexico that could possibly develop into a depression. Yesterday was the peak of the hurricane season. In the midwest, a cold air mass will plummet temps into the 40's with a gusty northwesterly chill.
Tropical Storm Gabrielle made landfall today over the Outer Banks in North Carolina. The system came ashore as a weak storm only causing some gusty winds and rain. The storm strengthened just a bit this morning but still didn't pack a punch. The parched southeast is also in desperate need of rain. All 100 counties are facing drought conditions — 91 in a severe drought or worse. .Gabrielle will make sharp turn to the north and head back out to sea without effecting any other landmass. A tropical storm warning was issued from Hatteras to the Virginia border. The greatest danger with this storm will be the rip currents along the coast. photo: Emerald Isle, North Carolina
Heat and humidity are expected to build this weekend in the East. Temperatures will soar into the upper 80's by Friday and near 90 on Saturday in most eastern locations. Along with the warm up also comes the threat of a tropical system which would be named Gabrielle. Is it going to happen? Models show weakening but only time will tell. Currently, the center of circulation lacks any tropical features. This is due to excessive wind shear over the past few days. As high pressure starts to settle in on Friday, the winds aloft will subside and allow the low to form into a depression. Current models are still forecasting the tropical system to curve once it hits the Carolinas and move eastbound. Stay tuned for more info. graphics courtesy of Accuweather

As the week progresses, it's more imminent that Gabrielle will form in the next 36 hours. The models are all starting to pull more evidence that this storm will approach the Carolinas by weekend and up the coast by Monday. The GFDL and the GFS are predicting the system will make a loop in the Atlantic then back seaward to the coast. At this point it is pretty certain that it will develop into a named storm. The low has a clear low-level circulation center and steering currents are very weak, which will give the storm an opportunity to drift and build. As the storm develops more information will come in.

Forecasters are watching an area of low pressure off the South East coast very carefully. The GFDL shows this area of low pressure developing into a tropical storm, which would become Gabrielle. The GFDL is a an advanced 3-dimensional weather forecast model developed specifically for predicting hurricane movement. GFDL stands for Geophysical Fluid Dynamics Laboratory Model. High pressure is starting to build into the Northeast which would keep the disturbance to the south and east over very warm water. We will continue to keep on eye on this into early next week. GFS model is showing similar development. Stay tuned for updates.
Hurricane Felix produced an impressive eye and major intensification over Sunday night. Hard to believe, but Felix too will go down in the record books as the second fastest 12-hour pressure fall. The pressure dropped 50 millibars between 11 am and 11 pm EST Sunday. Wilma dropped 83 millibars in 2005. The center of circulation 275 miles south of Kingston Jamaica and continues to move westward at 22 mph. Hurricane watches and warnings are in effect for Honduras and Belize.
A major blast of hot air is backing into California which will send temperatures soaring into the 90's and 100's. Today is the seventh day that the heat wave has contributed to blackouts and no AC. All eyes are on energy companies as they run into supply issues over the next week. Temperatures hit 108 in the Hollywood Hills and in the 110's int he desert. Typically we see cool Pacific air dominate much of the coastal communities. However, as high pressure builds over the south west, there won't be any onshore flow. Warming winds from the west will cut off any marine layer that tends to build on the coast. Temperatures are the inland areas of southern California should reach around 100, that includes San Diego.
