Tropical Storm Lee is located about 40 miles WSW of Baton Rouge. It is moving NNE at 8 mph. Winds remain near 45 mph with higher gusts. We had a wind gust of 43 mph at the Baton Rouge Metro Airport around 10 and 11 AM. The pressure is up to 987 mb.
The drier air that was being filtered into Lee is beginning to be cut off by showers wrapping around the southern half of the center of the storm. The rain bands have been coming in waves through the WBRZ viewing area, and will do this all day long. Heavy rain will continue with additional rain fall totals around 2-4 inches today. This will cause more flash flooding from time to time today.
Here are the Baton Rouge Impacts:
Heavy Rain...extremely heavy rain can be expected all over South Louisiana today as Lee moves inland. Rainfall rates could still be 1 to 3 inches an hour! Rainfall totals between now and Monday could be around 7-12 inches around the WBRZ viewing area. We could pick up an additional 2 to 4 inches today. Baton Rouge Metro Airport has received over 6.00" of rain since Saturday. Other WeatherNet 2 sites have also picked up 7"+ of rain across Livingston , Tangipahoa, and St. James Parishes. Due to all of the excessive rain, the NWS has issued a Flash Flood Watch in effect through Monday Night.
Flooding...we could see some flooding of low-lying areas, and in local rivers. We will have to keep an eye on the Comite, Amite, Tickfaw, and Tangipahoa Rivers the next few days as they are expected to rise to close to flood stage. Also, area roads that typically flood are already holding water, so please DO NOT drive through flooded roadways. There's no way know how deep the water is. As the saying goes, "turn around, don't drown." Some low parts of I-10 have taken on water from time to time. Also, parts of Nicholson Road have taken on water during the last 2 days, along with roads around Livingston Parish.
Wind...A Tropical Storm Warning is in effect for the entire WBRZ Viewing area. This means that tropical storm force winds can be expected throughout today, tonight and tomorrow around the viewing area. These winds will cause trees to fall, and power outages will be possible. You can expect the winds to be around 20 to 30 mph with gusts to around 40 mph today and tonight.
Power Outages...Entergy & DEMCO have reported sporadic power outages around parts of East Baton Rouge, Livingston and Tangipahoa Parishes during the last 24 hours. Winds will be sustained around 20 to 30 mph with gusts to 40 mph later today, so that could cause some problems.
Tornadoes...The Tornado Watch has been extended for all of the WBRZ Viewing area until 4 PM. We had plenty of tornado warnings on Saturday, and we could have more throughout today and tonight. Anytime you have a land falling tropical system, tornadoes are very likely due to all of the spin in the atmosphere. These tornadoes are not like the typical ones we see in the Spring and Fall. Tropical tornadoes usually are very small, and do not last for very long. However, they can still produce damage!
Storm Surge...a surge is occurring along the Lousiana Coast with water water levels rising to as much as 3 to 5 feet. A surge of 4 feet was reported at Shell Beach, LA, and 3.5 feet in Lake Pontchartrain at New Canal Station on Saturday. Look for coastal flooding to last for a few days too.
