A concentrated area of heavier rains is expected over the Carolinas in association with the moisture channel to the east of Alberto.
Widespread 2-4” amounts will extend across much of the Southeast, and localized totals could be well above that range. Rainfall could total 4-8”, with localized amounts in the 8-12” range, over the western Florida panhandle and parts of southern Alabama and Georgia. Its remnants will continue north, reaching the Ohio Valley by Wednesday and southeast Canada by Thursday. As the storm moves northward through the Florida Panhandle and into Alabama on Monday night, it is expected to quickly decay into a subtropical depression. Heavy rains will be the main threat from Alberto over the next couple of days.

The heaviest thunderstorms with Alberto are located well to the east of the storm center, along a channel of moisture extending from Cuba to North Carolina.

The strongest winds will be east of Alberto’s center, with gusts above 40 mph and perhaps a few sustained winds in that range spreading across the Florida Panhandle and into far south Alabama and Georgia. With Alberto’s core convection weak and limited, and landfall only a few hours away, we can expect little if any significant change in the storm’s strength prior to landfall. Meanwhile, dry air from the western Gulf of Mexico had worked its way around the storm’s core and reduced the extent of showers and thunderstorms (convection) near the center. A conveyor belt of rich moisture well east of its center was fueling strong thunderstorms from Cuba across South Florida, with the moisture channel extending north to the mid-Atlantic. OAcJdrBERa- David Zierden May 28, 2018Īs is typical with a subtropical storm, Alberto had a highly asymmetric structure on Monday. Looks like the center of #Alberto passed directly over the Pensacola South buoy (42039). At 10:37 am EDT, Apalachicola, FL, reported southeast winds sustained at 28 mph, gusting to 44 mph. The buoy was reporting west winds below tropical storm force on Monday morning, suggesting that Alberto’s strongest winds are quite localized. The storm surge was running about 1.4 feet at Panama City at around 11 am.Īs the center of Alberto approached from the south on Sunday night, a buoy located about 130 miles south-southeast of Pensacola ( buoy 42039) reported top sustained winds of 45 mph and gusts to 58 mph. High tide passed at Panama City around 10 am, where astronomical tidal levels will be dropping until Monday evening. A storm surge of 2.8 feet was observed at Apalachicola just after 11 am EDT, and waters could hold steady or rise further between now and high tide in Apalachicola (around 3 pm EDT). A storm surge warning was in effect for the eastern portion of this area, from Mexico Beach to the Suwanee River. We'll have a new post on Alberto on Tuesday.Ī tropical storm warning was in effect for the north Florida coast from the Alabama border eastward to the Suwanee River. The depression was moving north at 12 mph. Alberto's center was located about 50 miles west-northwest of Dothan, Alabama. As of 11 pm EDT, Alberto had weakened to a subtropical depression, with top sustained winds of 35 mph.

Update (11 pm EDT Monday): Alberto made landfall around 5 pm EDT near Laguna Beach, FL.
Heavy rains and gusty winds from Subtropical Storm Alberto pushed into the Florida Panhandle on Monday ahead of a Memorial Day landfall. Above: Visible satellite image of Subtropical Storm Alberto as of 1522Z (11:22 am EDT) Monday, May 28, 2018.
