DISCUSSION AND OUTLOOK
At 400 AM CDT (0900 UTC), the center of Subtropical Depression
Alberto was located near latitude 32.3 North, longitude 86.8 West.
The depression is moving toward the north-northwest near 13 mph
(20 km/h). A faster northward to north-northwestward motion is
expected during the next few days. On the forecast track, the
center of Alberto will move over central and northern Alabama
through this morning. The system is forecast to move over the
Tennessee Valley later today and into the Ohio Valley and Great
Lakes region on Wednesday and Thursday.
Maximum sustained winds are near 30 mph (45 km/h) with higher gusts.
Continued weakening is forecast as Alberto moves farther inland, and
the system is expected to degenerate into a remnant low by Tuesday
evening. The Montgomery airport recently reported a wind gust of 43
mph (69 km/h).
The estimated minimum central pressure is 995 mb (29.39 inches).
HAZARDS AFFECTING LAND
RAINFALL: Alberto is expected to produce 2 to 6 inches of rain from
Alabama northward into the southern Great Lakes and from north
Florida into the southern Appalachians through Thursday. Isolated
maximum storm totals of 12 inches are possible over the Florida
Panhandle and Alabama. These rains may produce flooding and flash
WIND: A few gusts to tropical-storm force are possible across
portions of central and northern Alabama this morning.
TORNADOES: A tornado or two may occur today from southern Kentucky
to parts of Georgia.
SURF: Swells generated by Alberto will continue to affect the
eastern and northern Gulf Coast today. These swells are likely to
cause life-threatening surf and rip current conditions. For more
information, consult products from your local weather office.
