The Galveston County incident marks the latest death in connection with the Beryl disaster.
Four people died in Harris County, including a Houston Police Department employee who drowned while on his way to work.
Two Harris County deaths were blamed on downed trees - one in Atascocita, where officials say a tree fell on a one-story home and killed a man. The other death happened at a home in Ponderosa Forest near IH-45 and FM 1960, where 73-year-old Maria Loredo was in her home when a tree came crashing down, killing her.
Another death in Harris County happened in the 2600 block of North Main Street. Police said a 77-year-old man was driving on a bridge over White Oak Bayou when he drove onto a curb and tried crossing the high water. Police said the bayou's current pushed the man's vehicle against a wall, and it was submerged.
In Montgomery County, three people were killed during the storm. In one incident, a man and a woman were sleeping inside a tent behind a Dollar General when a large tree fell. The third death included a man who was on his tractor trying to clear a tree out of the way another tree fell onto him.
