Subtropical storm Alberto, the first named storm of the 2018 hurricane season, made landfall Monday afternoon near Laguna Beach, Florida.
Alberto is bringing heavy rain and flash floods along parts of the Florida Panhandle.
Alberto's top winds are 75 kilometers per hour. The storm is expected to dump as much as 30 centimeters of rain on parts of Florida, Alabama and Georgia.
But Alberto is likely to be a fast-moving, short-lived storm. Forecasters predict it will denigrate into what they call a "remnant low" by the time it moves inland toward the Tennessee Valley Tuesday afternoon.
The Atlantic hurricane season lasts from June 1 until the end of November.
Experts predict 10 to 16 named storms this year with up to nine developing into hurricanes, including as many as four major hurricanes.
Last year was an exceptionally busy hurricane season, with Hurricanes Harvey, Irma and Maria devastating Puerto Rico, Houston, Texas, and the Florida Gulf Coast.
