Rainfall totals of 3 to 6 inches with localized maximums of 10 inches are possible across the Southern Appalachians from northeast Georgia into the western Carolinas and from the upper coast of South Carolina into eastern North Carolina, the NHC said. Additional rainfall of 1 to 2 inches possible across the remainder of the Southeast into northern Florida.
A couple of tornadoes also are possible Saturday across eastern Georgia and the Carolinas.
Tracking Isaias
The previous eight storms have been tropical. NHC isn’t monioring any new systems.
Isaias became the latest-forming first hurricane on record in an update at 11:30 p.m. EDT Wednesday night. The previous record was set by an unnamed 1905 hurricane, which became a hurricane at 8 p.m. EDT on Oct. 7 in the Gulf. This was 60 years before satellites were used to track storms.
Only 1907 and 1914 failed to produce a hurricane.
