GOHSEP SPECIAL WEATHER REPORT
20 November 2014
As of: 1600 Hours
 
STATE EOC ACTIVATION LEVEL: 4 Normal Operations
 
SITUATION:  A line of thunderstorms is expected to move through the state on Saturday morning and continuing Saturday evening before tapering off Sunday. Most of central and south Louisiana will be under a SLIGHT risk of severe weather, with northern Louisiana under a MARGINAL risk.  Rainfall from 1 to 3 inches with isolated higher amounts will be possible are expected to occur within an 18-20 hour period. Also, there is a chance for some strong to severe storms, including tornadoes, damaging winds, and hail. The forecast areas for Louisiana have been broken down below.  
 
FORECAST for LOUISIANA 
Southwest Louisiana:  Showers and storms will become widespread on Saturday as a strong upper-level storm system approaches the region. At this time there is a slight chance for severe weather on Saturday and Saturday night, with large hail and damaging winds being the primary threats. Tornado activity will also be possible during this time. Dry weather is expected to return by late Sunday and continue through the early part of next week.

Southeast Louisiana: A vigorous storm system will bring the threat of strong and severe thunderstorms over the outlook area possibly as early as Saturday afternoon but mainly during the evening and overnight hours Saturday night. Confidence continues to increase in the risk of severe weather and all modes of severe weather will be possible. The main questions right now are the extent and severity of strong and severe weather.

In addition as this strong storm system develops it will lead to rather strong winds over both the coastal waters and inland areas. Winds over the coastal waters will increase as early as Friday with small craft advisories possibly needed. Winds will continue to increase overnight and more so Saturday with the possibility of a wind advisory needed.  This will also bring the chance of coastal flooding with tides 1.5 feet about normal through Sunday.

Central Louisiana: Showers and storms will become widespread on Saturday as a strong upper-level storm system approaches the region. At this time there is a slight chance for severe weather on Saturday and Saturday night, with large hail and damaging winds being the primary threats. Tornado activity will also be possible during this time. Dry weather is expected to return by late Sunday and continue through the early part of next week.

North Louisiana: Scattered showers and isolated thunderstorms will be possible as a upper level storm is expected to bring numerous thunderstorms to the region late on Saturday. Some of the storms could be severe.

Impacts/Precautions:

Damaging wind gust in excess of 60 mph which could down trees and power lines and/or cause structural damages. 
oWinds this strong can make driving difficult, especially for high profile vehicles and high rise bridges. Use extra caution.
oWinds over local waterways could be 5 mph higher than over land. Small boats will be especially prone to capsizing.

Isolated tornadoes 
oIf you receive a tornado warning, protect yourself and your family; seek shelter immediately.
