US: Adverse weather forecast across parts of the south and southeast through at least early July 14
Severe weather likely across parts of the southern and southeastern US through early July 14. Flooding and associated disruptions likely.
Event
Severe weather is forecast across parts of the south and southeastern US through at least early July 14. A developing convective system is expected to produce excessive rainfall across parts of the Lower Mississippi Valley and central Gulf Coast, which could trigger flooding across the affected area. Rainfall totals of up to 25 cm (10 inches) are possible in parts of central Mississippi, with totals of 2.5-15 cm (1-6 inches) likely across much of the affected area. Potential flash flooding and heavy downpours could trigger landslides on unstable slopes.
As of early July 13, the National Weather Service (NWS) has issued flood warnings and watches across parts of central Mississippi. The NWS's Weather Prediction Center has warned of a moderate risk (level 3 on a four-tier scale) of excessive rainfall across parts of central Mississippi through early July 14. There is a slight risk of excessive rainfall for much of the rest of Mississippi, as well as parts of southeastern Louisiana. southern and western Alabama, and the central and western Florida Panhandle. Officials could update and extend the coverage of weather alerts over the coming hours and 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-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.
