Washington, New York City and Boston also faced the heaviest downpours till Sunday evening. Another Storm Forecast The forecasters have warned that the new storm system will likely produce a thunderstorm, which may take the shape of a tornado, and affect the lower Mississippi River Valley on Tuesday. The storm may have an impact on over twenty-five million people, including areas such as southern Indiana and eastern Texas. The storm is feared to be stronger and more damaging and cause more fatality as it's likely to hit in the evening or night. The forecasters say that the severity of a storm largely depends on the time it occurs. Is it Normal Time for a Tornado to Hit? Tornados are more common in springs, though they hit the US anytime. It is caused by the mixing of temperatures as hot and cold air clashes in autumn generally. A category three storm was forecasted earlier this month in the US, rattling Texas, Louisiana, Arkansas and Oklahoma, which was later upgraded to category 4. If the storm is forecasted to hit on Tuesday levels category 4, this will be the first time two category four storms hit the US in November. Further Reading \t Planning to Travel on Thanksgiving?
