TEXAS — Here comes the rain again.

Still reeling from record rainfall in May, Texas is back in the bull’s-eye as Tropical Storm Bill closes in on the Texas Gulf coast Tuesday morning.

As far as tropical systems go, Bill isn’t terribly fearsome. Wind gusts will top 50 mph, but it’s the rain that has authorities worried.

The storm is expected to dump 4 to 8 inches in eastern Texas and up to 12 inches in isolated areas.

It’s bad news for a state already soggy from last month’s record-setting rains.

“While high winds and even tornadoes are possible, already wet grounds mean that even a moderate amount of rain will likely cause street flooding,” warned Harris County Emergency Management. “Bayous and rivers could go out of banks quickly, creating a serious threat to life and property.”

Harris County is home to Houston, the state’s most populous city.

In neighboring Galveston County, authorities issued a voluntary evacuation for the Bolivar Peninsula, which sits in Galveston Bay. Potential rainfall could flood roads on the peninsula, making it harder to leave later or for emergency responders to reach them.

Residents rushed to grocery and hardware stores, clearing the shelves of bottled water. batteries and booze.

“We bought the essentials for the storm,” a Sam’s Club shopper told CNN affiliate KTRK. “We got water, liquor and beer.”

School canceled

Dozens of school systems along the coast called off classes for Tuesday, including the Houston and Galveston Independent School Districts.

Preparations

Texas put its special operations center on alert ahead of the storm’s landfall.

“Any additional rainfall will exacerbate already saturated grounds, which could quickly lead to dangerous flash flooding and extended river flooding,” Texas Gov. Greg Abbott said in a statement.

Along the Gulf, the U.S. Coast Guard mobilized too.

“We got all of our helicopters, aircraft and boats in ready status,” Lt. Eric Vryheid, a U.S. Coast Guard pilot, told affiliate KRIS.

“We’re taking the storm seriously,” said Vryheid. “We urge that the community takes it seriously as well. We don’t want anyone getting caught in an unsafe situation.”

The forecast

Foresters say Tropical Storm Bill will quickly weaken after coming ashore Tuesday morning. It will linger in the region through Wednesday.

The heaviest rainfall will soak eastern Texas and Oklahoma — 4 to 8 inches will be the norm. Parts of western Louisiana and Arkansas will see 2 to 4 inches.

Last month

The state has barely recovered from May’s record-setting rainfall.

Torrential rains dumped 37.3 trillion gallons of water on the state during the month, enough to cover the entire state with 8 inches of water, according to the National Weather Service.

Last month’s storms killed at least 43 people in the United States and Mexico.
