As of 7:15 a.m., the National Weather Service in Miami said Alberto, the first-named storm of the 2018 season - which technically begins Friday, but who's counting? - had its center now located about 100 miles east of Cozumel, Mexico, in the northwestern Caribbean Sea. Tropical Storm Warnings have been issued for that area.
A Storm Surge Watch is in effect for Crystal River in Florida to the Mouth of the Pearl River in Mississippi.
Alberto's track shows it making landfall along the Gulf Coast possibly late on Monday.
Although the east side of the storm isn't expected to reach Broward, Miami-Dade or Palm Beach counties, the storm's outer bands are expected to bring the area heavy rain, gusts of more than 40 miles per hour, strong rip currents and the possibility of tornadoes, according to a briefing by the National Weather Service in Miami.
The center has re-formed north of the western tip of Cuba.
Storm Alberto has continued roiling toward parts of coastal Mexico and Cuba with rip currents and risky surf on Saturday.
Heavy rains will begin to affect the central Gulf Coast region into the southeastern United States on Sunday and continue into the middle of next week as Alberto moves northward after landfall.
The latest advisory has Alberto with winds of 40 miles per hour. A sub-tropical storm means the center of circulation is exposed and the rain and thunderstorms are pushed away from the center.
Heading into the second half of the Memorial Day weekend, all eyes remain on the Gulf as Subtropical Storm Alberto approaches the Big Bend of Florida before curving west towards the Alabama shoreline. Isolated tornadoes were also possible.
Alberto is the first named storm of the 2018 hurricane season.
The National Weather Service said a flash flood watch would be in effect from Saturday evening through Tuesday evening for southeastern MS, southwestern Alabama and the western Florida Panhandle.
With the threat of flooding, it's a good idea to see if your property is in a flood-prone area. About 5 to 10 inches of rain are possible along affected areas in eastern Louisiana, Mississippi, Alabama, western Tennessee and the western Florida Panhandle.
Because of it's poor organization and some cooler temperatures in the upper levels of the atmosphere, Alberto has been designated a subtropical storm.
The next advisory will be released at 4 p.m.
Hurricane season doesn't formally start until June 1.
