A potent storm system moving across the country is threatening to bring flooding rains, high winds and hail to portions of the Midwest and Ohio Valley over the weekend. Thunderstorms that produced wind gusts in excess of 55 miles per hour in southern Oklahoma Wednesday night are moving northeast to threaten several states Friday and possibly into the weekend.
The high winds from these storms are powerful enough to bring down entire trees and powerlines to cause power outages and possible damage to buildings. In addition to the winds, these storms are capable of dumping a lot of rain in a short period of time. Run-off can cause creeks and streams to rise rapidly and if that happens, roadways can quickly become flooded. There is also the possibility of flooding in low-lying areas and in areas with poor drainage.
Severe storms delivered a frightful Halloween across the center of the United States Thursday as torrential rainfall flooded central Texas and threatened tornado activity in numerous states. Up to 14 inches of rain fell in central Texas, killing one person who was swept out of his vehicle in the Austin area. Dozens of people were evacuated from flooding that swamped hundreds of homes in the state capital.
Scores of cities in the US postponed Halloween trick-or-treating on Thursday as the storm that flooded Texas churned northward toward the Great Lakes. High winds were the primary reason many communities in central Tennessee canceled outdoor Halloween plans Thursday. A 9-year old boy lost his life Thursday night in Nashville when he came into contact with a live downed power line. The boy’s death happened on a day of severe weather that put an end to many Halloween festivities in Tennessee.
At one point during the night on Thursday, over 14,000 Nashville Electric Service customers were without power. The National Weather Service had a wind advisory in effect for central Tennessee as winds in excess of 45 miles per hour were expected Thursday night. The service said that any severe weather over that state would be isolated but high winds were likely to be widespread.
Much of Kentucky was under a tornado watch Thursday night as was central Tennessee. The National Weather Service issued the watch after 8pm and expected it to last until about 2am on Friday.
