Tropical Depression 9 has strengthened into Tropical Storm Hermine

Tropical Depression 9 has strengthened into Tropical Storm Hermine with 40 mph winds. It is producing more convection today and is a little better organized. This is due to less wind shear moving over the system.  You can see outflow on the satellite images, and this is a sign that the storm is getting better organized.  Hermine will continue to slowly get stronger today as it moves over very warm water temps. in the upper 80s. with only moderate wind shear over the system.  It is currently stationary, and that is ok.  This just lets the trough of low pressure dig deeper across the Eastern U.S., and it will be pulling Hermine to the NNE later this evening.  

The trough of low pressure over the Eastern U.S. and will continue to pull Hermine to the
north and NE through Thursday.  At the same time, a cold front will also be moving south with the trough to help send Hermine away from Louisiana and into the Florida Panhandle.  While this is happening, Hermine will go through some moderate wind shear and the upper 80° water temperatures.  This will cause it to get stronger with winds likely around 65 mph as it moves NE toward the Florida Panhandle. Once it gets closer to shore, it will encounter some strong wind shear from the trough and cold front.  This will prevent it from getting too strong as it makes landfall.

Tropical Storm Warnings have been issued for parts of the Florida Panhandle and Big Bend
area stretching from Panama City east to just north of Tampa.  This is the area that will see tropical storm force winds and a storm surge around 3 to 5 feet. 

Then this system will quickly move over FL and GA and emerge in the Atlantic Ocean near Charleston, SC on Friday. 

Labor Day Weekend: If you are traveling to Destin or
Panama City for the long holiday weekend, the weather will be pretty good.  I would delay your trip until Friday vs going on Thursday.  Friday through Monday will be partly to mostly cloudy and hot with a 30-40% chance for storms each day as the cold front stalls over the I-10 corridor and dissipates.  Overall, it will be some decent weather at the beaches. 

Be sure to check back with my blog updates and my posts on Facebook, Twitter and on WWL-TV over the next few days. Stay weather aware! -Dave

Major Snowstorm Headed To Northeast US Tomorrow

For all of my friends and family that live in the Northeast US...here is my latest analysis of the winter storm heading your way on Friday into Saturday: The same area of low pressure that brought the heavy rain and thunderstorms to Louisiana last night and this morning will be moving up the East Coast on Friday.  It will get much stronger and become a  Nor' Easter that will impact all the major cities from Philly to NYC to Boston as well as inland areas. Delmarva to NJ Coastal Areas :  Winter Storm Warning in effect from Friday AM until Saturday AM!  It looks like it will start out as a brief period of snow along the coast in the morning then change into a windy rain during the day.  Then go to a heavy snow late Friday into Saturday Morning.  Snow accumulations of 4-8" are possible.  Some minor ice accumulations are possible too. Winds will be sustained around 30+ mph and coastal erosion will be possible too. NE PA : Winter Storm Warning from 10...

The Unseasonably Cool Weather Continues

Short Term Forecast :  It is a very cold morning across the Capital City with clear skies and temperatures in the 30s.  A light freeze is expected!  I hope that you brought in your plants last night.  Take that jacket with you this morning. An area of high pressure remains over the Southeast U.S. today.  This will keep us sunny and with the northwest winds over us, we will stay cool.  High temperatures will be in the upper 50s. Another freeze is expected tonight for the Baton Rouge area.  We will be clear with calm winds and very good radiational cooling.  Low temperatures will fall into the upper 20s to lower 30s.  The NWS has issued a Freeze Warning for areas along and north of the I-10/12 corridor from 2 AM to 8 AM Wednesday Morning.  The freeze could last 2 to 6+ hours and that would be long enough to kill any vegetation.  Make sure you bring in your plants or at least cover them tonight!  Bundle ...

Today Is The 5th Anniversary of Hurricane Gustav

Early in the morning on September 1, 2008, Labor Day, Hurricane Gustav made landfall near Cocodrie, LA.  It was a strong category 2 hurricane with 110 mph winds.  At one point, right before Gustav made landfall over Western Cuba, winds were as high as 150 mph (Category 4).  It did weaken as it crossed Cuba, but did regain strength as it sat in the middle of the Gulf as it became a Category 3 storm with winds of 115 mph.  This storm became the worst one ever to impact Baton Rouge, LA.  Sustained winds around 70 mph with a 91 mph wind gust was reported at Baton Rouge Metro Airport, 108 and 117 mph wind gusts were reported in Houma, LA.  That caused significant damage and, at one point, the entire city of Baton Rouge was without power. Hurricane Gustav moved slowly inland and the eastern-edge of the eye wall moved along the Mississippi River into Baton Rouge.  It continued northward through West Feliciana & Pointe Coupee Parishes.  The worst...
