AUSTIN (KXAN) — A now weaker Tropical Depression Nicholas continues to crawl east into Louisiana, bringing heavy rain and flooding concerns to the Southeast U.S. midweek.

STORM HISTORY: Tropical Storm Nicholas strengthened to a Category 1 hurricane late Monday night before making landfall early Tuesday morning. Nicholas had maximum sustained winds of 75 MPH and gusts near 90 MPH at landfall near Sargent Beach, Texas on the eastern Matagorda Peninsula. The storm then quickly transitioned back to a tropical storm by 4AM Tuesday.

IMPACTS: Nicholas dumped 6″-14″ of rain across southeast Texas Monday into Tuesday with the highest totals recorded in the Galveston Bay area. Storm surge reached up to 6′ in Manchester, TX, the 4th highest on record for the area (records dating back to 1995), and surges of 3′-5′ were recorded along the Texas coast between Matagorda Bay and Galveston Bay. Winds of 70-75 mph were also observed in Galveston and the Port O’Connor area.

More than 30,000 customers were without power in the southeast part of Texas Wednesday morning, down from the half a million customers dealing with outages after landfall Tuesday morning.

FORECAST: The main threats moving forward will be the heavy, flooding rain as Nicholas slows to <5 mph while crossing the TX/LA stateline. The storm will generally move to the east through the day Wednesday before making a hard left turn to the north on Thursday.

Flash Flood Watches continue for most of southern Louisiana, Alabama and Mississippi until Thursday.
