Tuesday Morning: Nicholas to bring heavy rain & flash flooding to Louisiana

Weather

Today-Tomorrow: Heavy rain is expected throughout the day thanks to Hurricane Nicholas. The out and middle bands will soak us throughout the day as it inches closer to Louisiana. Tomorrow it is expected to come to a crawl as it approaches Lake Charles. This will bring more heavy rain for tomorrow and likely training rain bands in many areas. Flooding is a high concern with a FLASH FLOOD WATCH in effect today for everyone until Thursday morning. Isolated tornadoes may also be possible. Wind will not be a huge concern. Nicholas made landfall as a category one hurricane but the core of the storm (where the strong winds are found) will only be at tropical depression or subtropical depression strength when it nears Louisiana. Highs will be right around 80 due to the cloud cover and heavy rain. No sunshine is expected with cloudy skies staying in place.  

Thursday: At this point Nicholas will likely be a tropical or subtropical depression centered somewhere near Lake Charles or Baton Rouge. Its hard to say for sure. It is expected to move very slowly in Louisiana and in no particular direction. A ridge of high pressure that is steering Nicholas will dissipate, leaving the storm with nothing to steer it as it moves through Louisiana. The hope is it will begin to lose its moisture content on Thursday so that the rain isn’t so heavy or widespread on Thursday. 

Friday-Sunday: Isolated to scattered showers and thunderstorms are possible with highs in the mid-to-upper 80s after Nicholas exits Louisiana. When this happens however, is still uncertain since Nicholas is losing its momentum with nothing to steer it.  

Tracking the Tropics: Another system in the tropics is worth watching. A tropical wave off the west African coast is quickly becoming organized and is likely to develop into a tropical depression or tropical storm as it tracks westward across the open Atlantic and towards the Caribbean.  

No other tropical systems are of concern for Baton Rouge.
