Houston first responders noted an uptick in vehicle crashes Wednesday after snow melted and refroze overnight, worsening road conditions due to black ice.

Houston Mayor John Whitmire is holding a press conference to provide the latest information on the winter storm in the area this week.

A woman killed in a car crash and a man found dead in a Katy parking lot were the first deaths reported in connection to the historic January storm.

A historic winter storm slammed the South on Tuesday, including in the Houston area where snow led to significant travel delays and brought daily life to a halt for millions. FOX Weather Meteorologist Kiyana Lewis was in Houston on Wednesday morning with the latest as temperatures remained well below freezing.

With freezing temperatures holding firm, much of Houston remains at a standstill, as schools, businesses and many roads remained closed Wednesday morning. State of play: Driving on roads is still not advised as melted snow has refrozen.
