DALLAS — The eastern half of Texas was preparing for renewed flooding as Tropical Storm Bill approached the Gulf Coast.

The National Hurricane Center predicted the storm would make landfall this morning somewhere between Baffin Bay, south of Corpus Christi, and High Island, just up the coast from Galveston.

Galveston County officials already have directed voluntary evacuation of the low-lying Bolivar Peninsula, where Hurricane Ike wiped out most structures in 2008. School districts from Galveston to the Houston suburbs canceled today’s classes.

According to projections by the National Weather Service, parts of North Texas, Arkansas and Oklahoma could get up to 9 inches of rain over the next five days, and Missouri could get more than 7. After last month’s historic rains and floods, the forecast was expected to complicate ongoing flood-containment efforts.

“If we get that much rain in that time, there’s probably going to be a resurgence of flooding along these rivers,” said Kurt Van Speybroeck, meteorologist for the weather service in Fort Worth.

Memorial Day weekend storms brought widespread flooding to Oklahoma and Texas, killing more than 30 people. At one point last month, 11 inches of rain fell in some parts of the Houston area, resulting in flooding that damaged thousands of homes and forced motorists to abandon at least 2,500 vehicles.
