Tropical Storm Hanna was upgraded to a hurricane Saturday, moving toward the Texas coast and threatening to bring heavy rain, storm surge and possible tornadoes, all while another tropical storm approaches the Caribbean.

Hanna is the first hurricane of the 2020 Atlantic hurricane season, the U.S. National Hurricane Center said in its Saturday morning update. Maximum sustained winds had increased to 75 mph. The storm was centered about 100 miles east-southeast of Corpus Christi, Texas, and was moving west at 9 mph.

A storm surge warning in effect from Baffin Bay to Sargent was extended south of the bay to Port Mansfield, Texas. Storm surge up to 5 feet was forecast for that area. People were advised to protect life and property from high water.

Tornadoes were also possible Saturday for parts of the lower to middle Texas coastal plain, forecasters said. A hurricane warning remained in effect for Port Mansfield to Mesquite Bay, and a tropical storm warning was still in effect from Barra el Mezquital, Mexico, to Port Mansfield, Texas, and from Mesquite Bay to High Island, Texas.

Forecasters said Hanna could bring 6 to 12 inches of rain through Sunday night — with isolated totals of 18 inches — in addition to coastal swells that could cause life-threatening surf and rip current conditions.

Gonzalo and Hanna broke the record for the earliest seventh and eighth Atlantic named storms, respectively, according to Colorado State University hurricane researcher Phil Klotzbach. The previous records were Gert on July 24, 2005, and Harvey on Aug. 3, 2005, Klotzbach said.
