GREENVILLE, Miss.--A decision by the Greenville City Council Thursday afternoon has the city under a state of emergency for at least 30 days following damage by the storms that moved through the state Wednesday.

Damage in and around the city may have been caused by a tornado. National Weather Service survey teams are still out today trying to find out just how much damage was caused by twisters, versus straight-line winds.

The ninth grade building on the campus of Greenville-Weston High School is missing part of its roof, and that means there will be no school in the district until Monday. Parts of other buildings on the campus were also damaged.

At peak, there were 4,000 customers without power. There are still some people in the dark today.

A local state of emergency was also declared Thursday in Scott County, where crews are working to clean up damage left behind by Wednesday's strongest tornado, an EF3, with winds of at least 135 mph.
