NWS warns about heavy rains, coastal flooding
Significant rainfall flooding and coastal flooding is expected in southeast Texas and southwest Louisiana on Sunday.
The National Weather Service in Lake Charles is forecasting 5-7 inches of rain across the region, with the highest rain totals along and south of the I-10 corridor of southeast Texas and southwest Louisiana. Locally higher amounts are possible. During the times of heavy rain, expect to see street flooding on Sunday.
In addition, tides along the southeast Texas and southwest and south central Louisiana coast will run high on Sunday, topping out between 5.0 and 5.5 ft MLLW during high tide. This will result in coastal flooding in low spots in and around Sabine Pass, lower Cameron Parish, Intracoastal City, Cypremort Point, and Burns Point.
The combination of coastal flooding and heavy rain will cause backwater flooding in parts Jefferson and Orange counties near the Neches and Sabine Rivers, Hillebrandt, Taylor, Adams, and Cow Bayous, and along the Calcasieu River and Black Bayou in Calcasieu Parish. Delcambre and Franklin will need to watch for backwater flooding as well.
