LOUISIANA WEATHER - October 26, 2010

Statewide Burn Ban

On Thursday, October 21, 2010, Governor Jindal issued a State of Emergency – Proclamation No. 84 BJ 2010 – Imminent Threat of Wildfire posed by continuing drought conditions.
The proclamation can be viewed at the following: http://www.gov.state.la.us/index.cfm?md=newsroom&tmp=home&catID=8

The State Fire Marshal, Butch Browning and Dept. of Agriculture and Forestry Commissioner Mike Strain, have issued a cease and desist order for all private burning, pursuant to his authority under R.S. 40:1563. This order is effective as of October 3, 2010, and shall remain in effect until rescinded.

SOUTHEAST LOUISIANA: Today and Wednesday will be partly cloudy to sunny with a 20-30 percent slight chance of showers each day. Thursday through Saturday will be mostly sunny with clear evening skies each day
Temperatures: Today: 87/72, Wednesday: 88/68, Thursday: 82/47, Friday: 74/44, Saturday: 75/50.
HAZARDOUS WEATHER: A tight pressure gradient will result in strengthening winds across the area today. Sustained winds of 20 to 25 mph with gusts in the 30 to 35 mph range are expected through this afternoon, especially for areas along and west of the interstate 55 corridor and areas south of the tidal lakes. This could cause hazardous driving conditions on elevated roadways. Isolated thunderstorms will be possible this afternoon. Severe weather is not expected, but one or two storms may become strong. Strong winds over the gulf waters and tidal lakes will cause hazardous conditions for small craft through most of today. A small craft advisory is in effect for the open waters of the Gulf of Mexico. An exercise caution headline is in effect for the tidal lakes as well as Lake Borgne and the Mississippi sound. Conditions should improve late this afternoon as the pressure gradient begins to relax.

Isolated to scattered thunderstorms will be possible through Thursday. A few storms could become strong. A very dry air mass combined with strong winds behind a cold front on Thursday will result in dangerous fire conditions, especially on Thursday and Friday.

Small craft advisories may be needed Thursday and Friday due to strong winds following a cold frontal passage.
