Monday Evening Tropical Depression 9 Update

Tropical Depression 9 still remains disorganized in the far Southeast Gulf of Mexico.  It is still battling wind shear and dry air thanks to an upper-level low over the NW Gulf. This is the same upper-level low that brought Louisiana rain the last few days. Winds are sustained at 35 mph according to the Hurricane Hunters.

Due to the disorganized nature of TD 9, I'm only expecting it to only get a little stronger in the next 24 hours.  It will be moving into warm Gulf Waters and the wind shear will be a little less than it is right now. Forecast now calls for it to become a minimal tropical storm on Tuesday with 40 to 45 mph winds. It will likely get the name Hermine (her-MEEN).
I'm still expecting the upper-level area of high pressure to move toward the Plains States. At the same time, a trough of low pressure will be over the East Coast, and it will send a backdoor cold front down to the Southeast U.S. As TD 9 moves into the Central Gulf, it will be pulled north by the trough. It is forecast to get a little stronger at this point, but still remain a tropical storm. Then as it moves closer to the Northern Gulf Coast, the cold front will help deflect it to the NE into the Big Bend area of Florida with landfall around Thursday Afternoon. It will still get a little stronger before landfall and could be a strong tropical storm with 65 mph winds. Then it will cross Florida and move across the Atlantic. The forecast models are starting to come into better agreement with the forecast too. That is great news!
It is looking more and more like Louisiana will be in the clear with this storm! I still wouldn't put your guard down yet. I will feel more comfortable giving us the all clear once it stops moving west and turns to the north.  This should happen on Wednesday.  We will feel some impacts like higher coastal tides around 2 feet above normal for a few days with some strong easterly winds. Once the storm moves NE the tides will go down as northerly winds will be back.  We will also have some "drier" weather Thursday and Friday as dry air moves down from the north over us too! It won't be a huge break in the humidity, but we will take what we can get! Even the weekend doesn't look bad with only a slight chance for storms as the cold front will be along the Northern Gulf Coast. Overall, we should have some nice weather for Labor Day Weekend! 

 Please continue to follow my updates here, on Facebook, Twitter and on WWL-TV.  I'll have a full update on Tuesday Morning on WWL_TV. 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...
