Flash Flood Watch in Effect through Late Saturday

Friday, April 13, 2018

St. John the Baptist Parish – The National Weather Service has issued a Flash Flood Watch for Southeast Louisiana and Mississippi until 1 am Sunday, April 15, 2018 as a result of a slow-moving low pressure system traveling ahead of a cold front.

According to forecasters, the main time frame for severe weather to impact the area is Saturday morning through the early evening hours. Threats associated with this system include heavy rainfall that could lead to flash flooding, hail, strong winds which could down trees and powerlines and the possibility of tornadoes. Showers and thunderstorms producing heavy rainfall could produce 2 to 4 inches of rain, with locally higher amounts in excess of 6 inches possible.

Residents are asked to remove debris from catch basins and storm drains and clear yards in advance of anticipated rainfall and to assist with drainage.  Remember, if you encounter flooded roads, turn around, and never attempt to drive down flooded roadways.

 A Flash Flood Watch means that conditions may develop that quickly lead to flash flooding and ponding of water. Residents should monitor later forecasts and be prepared for rapidly changing conditions including taking action should Flash Flood or Tornado warnings be issued.

Please also dial 911 to report flooding or concerns so that it can be properly reported and a crew dispatched. To sign up for Parish alerts, visit and click on “Stay Connected.”
