Coast Guard officials say crews are continuing their search for at least four people missing in the water after a powerful storm capsized several sailboats participating in a regatta near Mobile Bay, Alabama.

Petty officer Carlos Vega says the storm rolled through the area about 4 p.m. Saturday and a man was plucked from the waters by the Coast Guard around 9 p.m. He said crews would search through Sunday morning, when they would reassess their strategy.

Vega said the Coast Guard also has established a temporary public information line in order to determine whether any additional people are missing. Anyone with information is asked to call 251-441-6602 or 251-441-6920.

More than 100 sailboats and as many as 200 people were participating in the Dauphin Island regatta in Mobile Bay. Dauphin Island Mayor Jeff Collier told Al.com (http://bit.ly/1GvR7pi) that at least one person was confirmed dead, but he did not know the cause.
