A low-pressure area in the Gulf of Mexico is expected to become a tropical cyclone and could cause tidal flooding along the coast from the Florida Panhandle to Texas, Reuters quoted U.S. National Hurricane Center Director Bill Read as saying on Thursday. "We've got a huge area of moisture, we've got a developing wind field ... we're probably going to see some tremendous rain amounts and the corresponding flooding that goes with that," Read told reporters in Miami. The Miami-based hurricane center is giving the system now over the central Gulf of Mexico and moving northwestwards a high chance of becoming a tropical cyclone during the next 48 hours.
