A crawling Hurricane Sally is threatening a 'historic rainfall event' in parts of the Gulf Coast

Automatic TRANSCRIPT

Is churning in the Gulf of Mexico this morning, sending rain squalls ashore. As a move slowly toward the coast. Sally's reign may be the biggest threat as a trudges toward the Gulf Coast. A slow mover will produce so much right. National Hurricane Center director Can Graham says part of the coast could see more than 15 to 20 inches of rain. That's a torrential amount of rain, a dangerous situation, he says. 110 Mile an hour winds will cause damage and power outages while the storm surge will inundate areas. Closest to the coast.
