PORTLAND, Texas (AP) - A spring storm has swamped parts of South Texas with more than a foot of rain and forced some classes to be cancelled.

The National Weather Service in Corpus Christi says parts of San Patricio County received 15 inches of rain in about a five-hour period Monday.

Forecaster Joel Veeneman (VEN'-uh-men) says street flooding has been reported in the Gregory and Portland areas.

Emergency management officials had no reports of anyone hurt.

The Gregory-Portland Independent School District called off classes Monday. School was expected to resume Tuesday, a time when forecasters say the rough weather system should be gone.

Veeneman says a cold front stalled over parts of South Texas, triggering a flash flood watch for the Coastal Bend until late Monday afternoon. The watch area includes Corpus Christi.
