Two people dead, others left stranded and trapped in the wake of Tropical Storm Imelda

Two deaths are linked to Tropical Storm Imelda, which flooded the Houston area Thursday and left hundreds stranded and in need of rescue, officials say.

Thursday's downpour reached up to 30 inches in some areas, said a National Weather Service representative, and drew comparison to Hurricane Harvey, which dumped more than 50 inches of water on parts of the Houston area and southeast Texas two years ago. The city of Houston received record rainfall with 9.18 inches of rain, according to a report by the National Weather Service.

Hunter Morrison, 19, died after being electrocuted and drowning while trying to move his horse, according to a Facebook post by a family member, shared by the Jefferson County Sheriff's Office.

Hours later, Harris County Sheriff Ed Gonzalez reported in a tweet that a man was removed from a submerged van and taken to a hospital, where he was pronounced dead. The man was driving toward the Eastex Freeway when he paused briefly and then accelerated in the water, which was about 8 feet high. Authorities found no other occupants in the vehicle once it was removed from the water.

Floodwater started to recede in most of the Houston area by Friday morning, said a National Weather Service representative.

In Harris County there were at least 1,700 high water rescues and evacuations, the Associated Press reports. Trapped by the floodwater, many people reported leaving their vehicles on area roads and freeways. More than 200 vehicles were towed in Houston as of Thursday night, Houston police Chief Art Acevedo said in a tweet.

About 120 people are housed in six storm shelters within Houston, the Houston Chronicle reports.
