Like Tuesday, the storms and downpours will be scattered in nature and not everyone will see them.
Several states, including Florida, Alabama, and MS went into pre-emptive states of emergency on Sunday, and a Tropical Storm Warning is in effect for the northern Gulf Coast from the Suwannee River to the Alabama-Florida border. With it, Alberto brings winds that are over 60 miles per hour, and over a dozen inches of rainfall.
Subtropical storm Alberto is pictured nearing the Florida Panhandle on Sunday.
The Accuweather spokesman observed that the weather event's classification, while not a pure tropical system, nonetheless is unsafe, and urged residents to take action to prepare their homes.
Jeffrey Medlin, meteorologist in charge at the National Weather Service's Mobile office, warned that even after the storm passes there will still be swells that could cause unsafe rip currents.
Alberto is expected to make landfall Monday in the Florida Panhandle. Extreme rainfall totals have been logged in Florida, Alabama, Georgia, western Tennessee and western Kentucky.
The National Hurricane Center in Miami said at 7 p.m. ET Monday that Alberto was centered about 10 miles west-northwest of Panama City, Fla.
"We've had a lot of rain, but we got lucky". A subtropical storm like Alberto has a less defined and cooler center than a tropical storm, and its strongest winds are found farther from its center.
Forecasters say what's left of the first named storm of the Atlantic hurricane season is still capable of causing flash flooding.
Meanwhile, potentially life-threatening rough surf and rip currents continued on the northern Gulf Coast after Alberto rolled up big waves and tides along the coast.
It hit on the last day of the Memorial Day weekend, complicating holiday travel.
Subtropical storm Alberto has fizzled into a subtropical depression as it rolled into Alabama, however forecasters warned of potentially risky flash floods even as winds dropped to 48km/h.
There's a chance Alberto could come ashore early Monday, said Dan Pydynowski, a meteorologist with AccuWeather Inc.in State College, Pennsylvania.
