Sunda Evening Update on Subtropical Storm Alberto

States of emergency were declared in Florida, Alabama and MS on Saturday as upwards of 15 inches of rain is forecast for the national Memorial Day weekend holiday. Maximum winds are sustained at 45 miles per hour.

By midday Sunday, the US Southeast was seeing 50-mile-per-hour (80-km-per-hour) winds and up to 10 inches of rain in some places, Ken Graham, director of the National Oceanic and Atmospheric Administration's National Hurricane Center, said in a video briefing. On Sunday there will likely be two areas where rain is more likely this afternoon in Central Alabama, with the earliest chance in Northwest Alabama and later in areas to the south and east.

Forecasters say Alberto was centered about 195 miles (315 kilometers) west of Tampa, Florida, at 7:30 pm. As the center of the storm approaches land, a dome of high pressure over the upper Midwest will slow it down.

A Tropical Storm Warning is in effect...

Alberto had picked up strength as it headed north through the Gulf of Mexico, bringing with it the warning of life-threatening inundation, said the Miami-based NHC.

After landfall, Alberto's winds will decay, but the moisture envelop and rainfall will continue northward through Alabama and eventually IN by Wednesday. No tornadoes were reported Sunday, however, in the Florida Peninsula.

There was some minor flooding in Wilmington Monday, but emergency officials are turning their attention to the mountains, where flash floods and risky landslides are possible as Alberto's remnants move to the west. The possibility of heavy rain, storm surges and flash flooding, however, pose hazards for residents.

The track for Alberto shows it aiming for the Florida Panhandle on Monday.

What is a tropical storm watch?

The slow-moving system is expected to cause wet misery across the eastern U.S. Gulf Coast over the holiday weekend.

Meanwhile, a Storm Surge Watch is in effect for the Suwannee River to Mexico Beach, Florida.

Precipitation will likely remain under a quarter of an inch, possibly higher if thunderstorms roll through the area.

Rainfall from Alberto will be heaviest in Florida, Alabama and Georgia. A few brief tornadoes were possible in much of Florida and parts of Georgia, South Carolina and Alabama. Although the center of the system will stay away from us, it will funnel in deep tropical moisture along the eastern seaboard.

Heavy rain from Monday through Wednesday poses a threat of localized flash flooding in the Triad area, the National Weather Service said.

The hottest temperature was in Madison, Minnesota, where it reached 102 degrees Sunday. "First half of the day will look soggy".

"As far as a nice sunny day overall, at the earliest, Thursday or Friday could be a little bit more sunny overall, " Moore said. "The risk for heavy rainfall and flooding will then spread over much of the southeast US tonight and Monday".
