Tropical Storm Erin has formed in the Atlantic and will continue to pick up strength over the next couple of days, according to the National Hurricane Center.
In a 5 a.m. ET advisory on Tuesday, Aug. 12, the hurricane center said Erin was located about 690 miles west of the Cabo Verde Islands with maximum sustained winds near 45 mph with higher gusts. Forecasters said Erin is moving west, and this motion is expected to continue for the next several days.
"Gradual strengthening is forecast over the next several days, and Erin is expected to become a hurricane in the next couple of days," the hurricane center said in the advisory, noting that there are currently no hazards affecting land, or watches or warnings in effect due to Erin.
Meanwhile, in the Gulf, a surface trough in the north-central Gulf is associated with a broad area of disorganized showers and thunderstorms. The system is not expected to develop before it moves inland, although locally heavy rainfall could produce flash flooding across portions of the Florida Panhandle, southern Alabama, southern Mississippi, and southeastern Louisiana over the next day or so, according to the hurricane center.
Lastly, the hurricane center said it is keeping an eye on a non-tropical area of low pressure located a few hundred miles southeast of Nova Scotia, Canada.
"Some limited tropical or subtropical development is possible over the next day or so as the low meanders near the relatively warm waters of the Gulf Stream," the NHC said, however the system is forecast to move northward over cooler waters, ending its chances of further tropical development.

NHC also keeping tabs on Hurricane Henriette in Pacific
Meanwhile in the Pacific, the NHC said it is keeping tabs on Hurricane Henriette.
In an 11 p.m. Hawaiian Standard Time advisory on Monday, Aug. 11, forecasters said Henriette was located about 730 miles north of Honolulu, Hawaii, with maximum sustained winds near 75 mph with higher gusts.
The NHC said further weakening is forecast during the next few days, with Henriette expected to become a post-tropical cyclone by early Thursday, Aug. 14. There are currently no threats to land stemming from Henriette.
How do hurricanes form?
Hurricanes are born in the tropics, above warm water. Clusters of thunderstorms can develop over the ocean when water temperatures exceed 80 degrees Fahrenheit. If conditions are right, the clusters swirl into a storm known as a tropical wave or tropical depression.
A tropical depression becomes a named tropical storm once its sustained wind speeds reach 39 miles per hour. When its winds reach 74 mph, the storm officially becomes a hurricane.
Prepare now for hurricanes
Delaying potentially life-saving preparations could mean waiting until it's too late. "Get your disaster supplies while the shelves are still stocked, and get that insurance checkup early, as flood insurance requires a 30-day waiting period," NOAA recommends.
