McAllen, Texas (AP) Forecasters don't expect Tropical Storm Dolly to turn into a major hurricane, but people in Texas are getting ready for bad weather.

Residents along the Texas-Mexico border are stocking up on plywood, generators and flashlights as emergency officials track a storm that could dump 10 to 20 inches of rain and trigger serious flooding.

A hurricane warning is up and Dolly could make landfall late today or early tomorrow.

Texas governor Rick Perry has activated 1,200 National Guard troops for storm duty.

During Hurricane Rita in 2005, more people died in accidents fleeing the storm than were killed by the severe weather on the Texas Gulf Coast.

Shell Oil says it's evacuating workers from rigs in the Western Gulf of Mexico.
