Isaac is finally a hurricane! It will continue to strengthen through landfall tonight. A Hurricane Warning is in effect from East of Morgan City, LA east to Destin, FL. A Tropical Storm Warning is in efect for Inland Parishes/Counties Around Baton Rouge.

Isaac is moving to the northwest at 10 mph and this track is expected to continue through landfall tonight over Plaquemines Parish, near Grand Isle, LA around Midnight Wednesday. It will continue to the northwest toward New Orleans on Wednesday Morning and then Baton Rouge on Wednesday Afternoon with tropical storm conditions over the Capital City. Then it will track toward Monroe, LA Thursday Night, and track into Arkansas by Friday.

What can we expect in Baton Rouge: The weather this afternoon will be mostly cloudy and breezy with scattered showers and thunderstorms as rain bands move across SE LA. Some of the storms will be strong to severe at times. Things will really start to go down hill tonight as Isaac makes landfall. Since it will be a slow-moving storm over SE LA, we will see a very long period of tropical storm force winds around 40-60 mph with higher gusts on Wednesday, very heavy rain totaling 6-12 inches with flash flooding likely, and the NWS has issued a Flash Flood Watch for all of Southeast Louisiana through Wednesday. We could also see a few tornadoes.

Lastly, power outages can be expected all across the Baton Rouge area starting tonight and possibly lasting for days. Please be prepared for that.

Coast Impacts: A storm surge of 6 to 12 FEET will be possible from the MS Coast to SE LA Coast including in the Lakes. Hurricane force winds of 75-85 mph and greater tonight into early Wednesday, then tropical storm winds Wednesday Afternoon/Night. Heavy rain around 10 to 20 inches will be possible! Power outages are also likely.

Lastly, stay calm and informed. Be sure to watch WBRZ, check out, and follow me on Twitter and Facebook for updates through today and Wednesday.

Stay Safe!!
