    As a storm responsible for violent thunderstorms and tornadoes in the Central states crawls along, the potential for severe weather will reach the mid-Atlantic and Southeast at midweek, threatening lives and property.

    While damaging storms will not hit every location from the Midwest to the South Tuesday, severe weather will put more than 70 million people at risk this day.

    In addition to the potential for tornadoes in the strongest storms, many of the storms will bring damaging wind gusts, frequent lightning strikes, hail and flooding downpours.

    AccuWeather meteorologists expect severe thunderstorms and tornadoes to re-fire Tuesday afternoon and evening over some areas of Mississippi, Alabama, Tennessee and Georgia that were ravaged by tornadoes on Monday.

    Meanwhile, damaging and life-threatening storms Tuesday evening will visit some areas farther east for the first time during this multiple day severe weather outbreak, including portions of Virginia and the Carolinas.

    A disturbance will rotate northeastward over the Midwest and can bring severe thunderstorms, including a few tornadoes to Indiana, Ohio, southern Michigan, Kentucky and West Virginia during Tuesday afternoon and evening.

    During Wednesday, the severe weather risk will include more than 35 million people from Ohio to the Carolinas and northern Florida but will expand northeastward into Pennsylvania, northern Virginia, Maryland and Delaware.

    Major cities in the path of the storms from Tuesday to late Wednesday include Detroit; Cincinnati; Cleveland; Charleston, W.Va.; Roanoke and Richmond, Va.; Charlotte and Raleigh, N.C.; Atlanta and Columbus, Ga.; Columbia, S.C.; Nashville and and Knoxville, Tenn.; Huntsville, Mobile, Montgomery and Birmingham, Ala.; New Orleans; Jackson and Biloxi, Miss.; Pensacola and Tallahassee, Fla.; Washington, D.C.; Baltimore; Pittsburgh and Philadelphia.

    An additional round of storms may affect the Atlantic Seaboard on Thursday from Boston, Hartford, Conn., and New York City to Wilmington, N.C., Savannah, Ga., and Jacksonville, Fla.

    Along with the possibility of storms with damaging wind gusts, frequent lightning strikes and hail is the chance of a few tornadoes. People will need to keep an eye on the weather and stay up-to-date with advisories, watches and warnings. If you believe that a tornado is approaching your location, seek shelter indoors in an interior room or basement.

    Motorists cruising along on area highways will want to keep an eye out for rapidly changing weather conditions. The storms will cross major highways such as interstates 20, 40, 64, 65, 70, 75, 77, 80, 81, 85 and 95.

    This is the type of situation, where much of the day may be cool and clammy, yet conditions can change rapidly to allow the formation of severe thunderstorms, including a tornado.

    In addition to the threat of violent storms, there will be a broad area of torrential rain that will fall over several hours and during a couple of days. Not only can this rainfall cause travel delays and cancellations of outdoor activities, but it can also cause flash, urban and small stream flooding.

    Some locations from the central and southern Appalachians to the Atlantic coast and Great Lakes may receive 3 to 6 inches of rain over a couple of days.

    Some of the rain will occur in the zone expected to be hit by severe thunderstorms. However, significant rain will fall north and east of the severe weather threat area over potions of upstate New York, the northern mid-Atlantic and New England.

    Generally cloudy and cool conditions will linger in the wake as the large storm system responsible continues to crawl eastward.

    By the time, the storm exits the United States, rounds of severe weather produced from it are expected to stretch seven days, from this past Saturday evening in parts of Texas and the southern Plains until Friday in parts of the East.

    According to Severe Weather Expert Henry Margusity, "Not only will this outbreak be the worst of the season so far, due to a sluggish start in severe weather, but it may end up being one of the worst outbreaks of severe weather for the entire season."

    The storms from Sunday to Monday have claimed the lives at least 28 people.

    More than 230 incidents of severe weather have been reported since Saturday evening, and the number of incidents is likely to more than double until it move out to sea this weekend.
