Tornado in Kenner and Metairie Yesterday

A supercell thunderstorm, or a thunderstorm that is rotating, developed over Ramah, LA yesterday.  A tornado watch was issued by the Storm Prediction Center (SPC) and numerous tornado warnings were issued as well for this storm.

The storm tracked just south of Baton Rouge over Plaquemine to Saint Gabriel to Prairieville and Gonzales.  It didn't produce a tornado around the Baton Rouge area, but did produce winds around 60-70 mph.  The only damage we could find were some downed trees and branches around Saint Gabriel, LA.  Meteorologist Ryan Davidson was there when it traveled over him.  The National Weather Service (NWS) will survey this area later today to see if it was straight-line winds or a possible tornado that caused this damage.

The storm continued down I-10 toward New Orleans and got stronger as it approached LaPlace, but still did not produce a tornado - even though the rotation was pretty strong.

Once the storm arrived in Kenner it looked incredibly impressive on radar as a classic supercell with a hook echo (radar image on left).  The rotation was very strong with about 90-100+ kt. gate to gate shear (Velocity image on right). These images were screen grabbed right after it passed over Kenner and was headed into Metairie:
  

It finally produced a tornado over Kenner and did some damage there.  It tracked east toward Metairie and also did some minor damage there.  Take a look at this picture sent by a viewer into WDSU-TV:

While this storm did produce a tornado, the damage was not as bad as it could have been.  The way it looked on radar I would have thought it produced some major damage.  We are very thankful that, that didn't happen.

This tornado was rated an EF-1 on the Enhanced Fujita Scale in Kenner and an EF-0 in Metairie according to the NWS Office in Slidell, LA.  This office serves the Baton Rouge and New Orleans areas.  Click here to read their report.

Remember, when we are on air saying there is a tornado warning take shelter IMMEDIATELY!  A rotating thunderstorm can produce a tornado at any time, but sometimes they don't.  You have to assume that it will and take your tornado precautions!

Always keep it tuned to WBRZ, BRZ Weather Channel, my Facebook and Twitter feeds for severe weather information!  -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 am Friday until 7 am Sat

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 up! Week Ahead :  The area of high pressure will stay put through

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 damage was seen along this line.  Area
