Heavy rain fell over portions of southern and southeastern Texas earlier this week as tropical moisture streamed northward from the Gulf of Mexico, causing flooding across much of the region. Corpus Christi and Weslaco, Texas were among the hardest hit by the flooding. 

Rain began falling across the region on Sunday and is continuing to fall, with some of the heaviest of the rain falling near Corpus Christi. Some areas have picked up nearly a foot of rain since Sunday morning, Below is a radar loop of storm total precipitation totals from Sunday morning through late Thursday morning from RadarScope.
