Isaac is still a tropical storm as it moves away from Baton Rouge, or 50 miles south of Monroe, LA with winds around 40 mph, pressure up to 989 mb. It is moving to the NNW at 9 mph. A Tropical Storm Warning remains in effect until further notice for all of SE LA.

It will remain breezy across Baton Rouge and Southeast Louisiana with winds around 20-30 mph and some higher gusts. We will have scattered light to moderate showers that will last throughout the day. A few strong thunderstorms are also possible as rain bands are moving up from the coast. These storms will produce very heavy rain and winds around 40-60 mph. Additional damage could come from these storms.

We could pick up an additional 0.5 to 1 inch of rain around Baton Rouge, but we could get up to 3 inches of rain in the stronger rain bands. A Flash Flood Watch remains in effect until 7 PM for all of Southeast Louisiana. Otherwise we will be mostly cloudy with high temperatures will be in the mid 80s.

The winds will diminish tonight to around 10-20 mph with a few higher gusts. We will have scattered showers with some heavy rain and mostly cloudy skies. Lows will be in the mid 70s.

Look for additional showers and thunderstorms on Friday as the rain bands will still stream from south to north around Isaac's circulation center across Baton Rouge. These could be strong at times with some heavy rain. We will see a few more peaks of sun and it will be hotter with highs around 90. Friday Night will be partly cloudy with a few showers. Lows will be in the mid 70s.

There are numerous power outages around town, so plan on bring without power for at least a few days.
