SOUTH PADRE ISLAND, Texas - In the end, Tropical Storm Don was little more than summer thunderstorms. Some scattered showers were expected to linger over parts of South Texas, but the area's best hope for substantial rain in months collapsed on approach Friday evening, drizzling the area with less than an inch of rain and strong breezes.

Officially the centre of Don remained just off the Texas coast at 8:40 p.m. CDT Friday (0140 GMT), but at that point it was little more than a low pressure system, said Lixion Avila, a senior hurricane specialist at the National Hurricane Center.

"It's a very weak system," Avila said. "It doesn't matter whether it makes landfall." Since Don never became a hurricane, the centre would not release a special landfall advisory. Its next scheduled update was scheduled for 10 p.m. CDT (0300 GMT). The cluster of storms was centred south of Baffin Bay in a sparsely populated area of ranch lands.

Cotton growers who scrambled to harvest in recent days, but still left the bulk of their fluffy bolls in the field could breathe a sigh of relief since National Weather Service stations in Corpus Christi and Brownsville said rainfall was about .5 inches (12.7 centimetres) in most areas. For other farmers and ranchers, it will be back to watching the skies longingly for rain.

"It was not nearly as much rainfall or wind as originally forecast," said National Weather Service meteorologist Joseph Tomaselli. "It would have badly damaged the cotton crop." The strongest winds recorded were about 36 mph (58 kph) at an offshore buoy, he said.

Onshore, meteorologist Lara Keys in the service's Corpus Christi office said winds gusted to 23 mph (37 kph).

Almost all of Texas is in extreme drought, and even Don's projected few inches of rain wouldn't have cured that, but at this point any moisture is appreciated.

"It was somewhat of a dud," said Carlos Cascos, the top elected official in Cameron County at Texas' southernmost tip. "It looked huge and powerful on the radar."

"We have another one out there that we'll be watching as well," Cascos said, referring to a new disturbance in the Caribbean.

Earlier Friday, storm preparations in South Texas were light with some people seeing it as a drill for things to come.

"In a way, this tropical storm is a pre-test for an actual hurricane," said Luis Canales of McAllen as he roped a grill and patio furniture to his brother's camper trailer at Isla Blanca Park at the southern tip of Padre Island. "It helps sharpen us up for what we need."

Cameron County asked people with RVs and other vehicles prone to taking flight in high winds to move them out of its parks on the island, but few seemed to be doing it.

Like Canales, Janie Rodriguez of Weslaco just secured loose items around her motor home at the park. She took down an awning but decided to leave a fishing boat, trailer and electric car with the motor home.

"They're saying it's OK to leave your trailers," she said. "I'm just picking up what would blow away with the wind."

The Padre Island National Seashore closed its beaches late Thursday. Nueces County, where Corpus Christi is located, restricted primitive camping on its beaches, and Texas A&M-Corpus Christi, Del Mar College and the University of Texas-Brownsville closed their campuses.

But an annual fishing tournament in Port Mansfield, north of Brownsville, began Friday as scheduled. The offshore division was cancelled, but fishermen still cast their lines closer to shore.
