MIAMI (AP) - The Latest on tropical storms (all times EDT):
Forecasters have issued a tropical storm warning for a long stretch of North Carolina's Outer Banks.
A public advisory from the National Hurricane Center says the warning is in effect for coastal areas along the barrier islands from Cape Lookout to Oregon Inlet.
Forecasters expect the tropical depression that's about 140 miles (225 kilometers) southeast of Cape Hatteras to become a tropical storm by early Tuesday. It will likely bring heavy rains and high winds to the islands along North Carolina's coast.
A tropical depression also was being watched in the Southeast as it churned across waters about 195 miles (310 kilometers) west of Key West, Florida. The Miami-based center said that system is also expected to become a tropical storm by sometime Tuesday.
Authorities at some locations in the Tampa-St. Petersburg area of Florida are hauling out sandbags to offer residents amid predictions of heavy rains from a storm system heading to the southeast Gulf of Mexico.
The tropical depression was located at 11 a.m. EDT Monday about 170 miles (275 kilometers) west-southwest of Key West, Florida, and moving west at 7 mph (11 kph) with top sustained winds of 35 mph (55 kph).
The National Hurricane Center said the storm is expected to eventually turn to the north and then northeast in coming days amid predictions it could drop heavy rains over northern Florida.
St. Petersburg says it began offering free sandbags Monday and will do so again for several hours Tuesday at two locations. Two other local jurisdictions also were making sand bags available.
