MONTGOMERY, Ala. (AP) — Forecasters say Alabama is at risk for a weekend of severe weather.

The National Weather Service says storms beginning over north Alabama early Saturday will create a threat of winds up to 60 mph and tornadoes through Sunday.

The Storm Prediction Center says there's an enhanced risk of bad weather in an area that includes Birmingham, Huntsville and Mobile, and Montgomery is on the fringe of the risk area.

Some weekend events already are being postponed because of the system. A concert by the rock bands Styx and REO Speedwagon that was set for Saturday night at The Wharf Amphitheater in Orange Beach is being until Monday.

The risk of storms shifts to southeastern Alabama on Sunday, but forecasters say severe weather isn't as much of a threat.
