US: Adverse weather forecast across the Ohio Valley region through early July 19
Severe weather likely across parts of the Ohio Valley, US through early July 19. Transport and utility disruptions likely.
Event
Adverse weather is forecast across parts of the Ohio Valley region through at least early July 19. Heavy downpours, large hail, high winds, and possible tornadoes may accompany severe thunderstorms. Heavy rainfall could trigger flooding in low-lying areas, and strong winds may cause property damage and power outages.
As of early July 18, the National Weather Service's (NWS) Weather Prediction Center (WPC) has warned of a moderate risk (level 3 on a four-tier scale) of excessive rainfall for portions of the mid Mississippi Valley and lower Ohio Valley and a slight risk for the rest of the affected area through early July 19. The Storm Prediction Center (SPC) has warned of a slight risk (level 2 on a five-tier scale) of severe thunderstorms across parts of the lower Missouri and mid Mississippi Valley over the same period. Officials could update and extend the coverage of weather alerts over the coming days.
The severe weather will likely contribute to transport disruptions throughout the region. Floodwaters and debris flows may render some bridges, rail networks, or roadways impassable, impacting overland travel in and around affected areas. Ponding on road surfaces could cause hazardous driving conditions on regional highways. Authorities could temporarily close some low-lying routes that become inundated by floodwaters.
Severe weather will likely trigger flight delays and cancellations at airports across the affected region. Flooding could block regional rail lines; freight and passenger train delays and cancellations are possible in areas with heavy rainfall and potential track inundation.
Localized business disruptions will likely occur in flood- or tornado-hit areas; some businesses might not operate at full capacity because of damage to facilities, possible evacuations, and some employees' inability to reach work sites. Strong winds could also cause power outages.
Advice
Monitor local media for updated emergency and weather information. Seek updated information on weather and road conditions before driving or routing shipments through areas where severe weather is forecast. Plan accordingly for potential delivery delays if routing shipments by truck through the affected area. Do not attempt to drive through flooded areas. Confirm flights. Charge battery-powered devices in the case of prolonged electricity outages.
