Here are the key messages for #Alberto as of 10 am CDT/11am EDT. Its winds, which had strengthened overnight to 65 miles per hour, were down to 60 miles per hour as of 11 a.m. Expect similar conditions in North Alabama on Tuesday as the center of the storm moves overhead; a Flash Flood Watch is in effect though noon Wednesday.
Alberto, the first named Atlantic storm of 2018, which spun up days before the formal June 1 start of the hurricane season, was packing maximum sustained winds near 105 kilometres per hour and was expected to drop as much as 30cm of rain, slamming an area from MS to western Georgia, the Miami-based hurricane centre said.
David Roth, a meteorologist with the National Weather Service, said: "Alberto has maximum sustained winds of 65 miles per hour (105km per hour), which is about 10 miles (16km) shy of being a hurricane".
The center also has discontinued all storm surge warnings for most of the state's peninsula. The storm, coming on the last day of the Memorial Day weekend, was expected to scramble holiday travel.
