Cristobal expected to impact Louisiana; Tropical alerts issued

Weather

Greatest threats will be heavy rain (inland flooding) and coastal flooding.

Latest information on Tropical Storm Cristobal as of 1 PM Friday

Tracking the Tropics: Tropical Storm Cristobal (Krees-TOH-Bahl) is moving to the north in the Gulf of Mexico. Models continue to show a landfall in Louisiana however, residents from East Texas to Florida will need to monitor because impacts can and will be felt away from the center and outside of the cone. Models show a tropical storm by landfall Sunday evening. Keep in mind, the timing may be adjusted in the coming 24 hours or so. It’s looking more likely that it will make landfall near the south-central and southeast Louisiana coastline, but either way, impacts will be felt well-away from the center, so please do not focus on the exact center of the cone. The extent of the tropical storm force wind field may be very broad due to it being very unorganized system.

Now is the time to prepare. If it holds onto the current track, Louisiana could feel tropical storm force winds as early as Saturday night, but most likely by early Sunday. All in all, this will mainly be a heavy rain and flooding threat.

A Tropical Storm Watch has been issued for parishes south central and southeast Louisiana – this includes Livingston, parts of Tangipahoa, St. Tammany, Ascension, Assumption, St. James, St. Martin, and more.

Tropical storm conditions are possible in these areas within the next 48 hours. This watch will likely be extended to include more areas in Louisiana in the coming hours. Be sure to check back in.

A Storm Surge Watch has been issued from Grand Isle, Louisiana, to Ocean Springs, Mississippi, including Lake Borgne. Storm surge of 2-4′ will be possible in these areas shaded in light pink.
A Coastal Flood Advisory has been issued to account for the possibility of inundation of 1-2′ above dry ground from high tide and persistent south and southeasterly wind. Also, heavy rain may lead to flooding.

POTENTIAL IMPACTS:

RAIN: Average 3″- 7″, Locally 10-15″+ in some feeder bands (If under a feeder band, our threat for flash flooding will greatly increase)

WIND: Winds of 30-40 mph with higher gusts will be possible. Power outages will be possible. Trees may be vulnerable from heavy rain and the wind.

TORNADO: Occasional tropical funnels and weak short-lived tornadoes.

COASTAL FLOODING & STORM SURGE: 2-4′ of storm surge from Grand Isle to Ocean Springs including Lake Borgne. Coastal flooding/storm surge will likely be an issue for coastal areas east of the center, especially east facing shorelines thanks to high tides and persistent south and southeast winds. Of course, this is also dependent on where the center of circulation tracks. This includes our tidal lakes, as well. Inundation of 1-2′ will be possible.

The National Weather Service has placed our area under a Flood Watch through Tuesday morning. Some areas may see over 10″ of rain through Tuesday.
Widespread rain totals will be around 3-6″ with some areas seeing over 10″
The Weather Prediction Center has placed our area under a Slight Risk (2 of 4) for flooding Sunday and into Monday
Tropical storm-force winds are most likely to be felt by Sunday morning, but as early as Saturday night.
