Tropical Storm Priscilla formed Saturday off the west coast of Mexico, where it was forecast to bring dangerous surf and possible flooding, the National Hurricane Center said.

Western Mexico was being lashed Monday by a hurricane bringing heavy rain, strong winds and rough surf to coastal areas and the Baja California peninsula.

Tropical Storm Jerry formed over the central Atlantic Ocean Tuesday and is expected to strengthen into a hurricane by Wednesday.

Hurricane Priscilla has strengthened to a Category 2 storm and is likely to become a major hurricane later Tuesday as it swirls off the Pacific coast of Mexico.

Forecasters warned of "steady strengthening," and Jerry is expected to become a hurricane within the next day or two.
