(CBS/AP) -- Two tornadoes have reportedly touched down in Alabama Friday, as a severe weather system continues to sweep across the state.
Emergency management officials told CBS News that one tornado has touched down in Limestone County, and another in Madison County heading towards an elementary school in Meridianville.
Madison County officials tell CBS News of "major damage to several houses" in the area of Harvest and Monrovia, but but there is no word yet on injuries.
The Associated Press is reporting that several houses were "leveled" in one neighborhood in the Walker Lane area.
An EMA officer told CBS News they are "in the middle of a life and safety event"
Huntsville Utilities is also reporting several large outages in northwestern Madison County reports CBS Affiliate WHNT.
The National Weather Service said severe storms are likely across north Alabama from Friday afternoon through Saturday morning. A tornado warning was issued Friday morning for east-central Limestone County and northern Madison County. The weather service said there's a chance of long-track tornadoes, strong winds, flooding and large hail.
The parts of the country at highest risk for tornadoes are north of Alabama in Tennessee and Kentucky, but the weather service says northern Alabama still has a medium risk for twisters. Chances of problems are less across the southern end of the state.
Twenty school systems - including the cities of Birmingham, Fayetteville and Russellville, and Colbert, Cullman, Etowah, Giles, Lauderdale, Lawrence and Walker Counties -are dismissing students early because of the possibility of strong storms.
