Columbia, S.C. – Drivers across the Midlands should prepare now for periods of heavy rain and isolated severe storms capable of producing 1.5 inches of rainfall and gusty winds along I-26 and I-20 through 8 p.m. Sunday.
According to the National Weather Service in Columbia, widespread rain will continue through the day, with most communities expected to receive between 1 and 1.5 inches by Monday morning. Isolated higher totals are possible, especially across the southern Midlands and the Central Savannah River Area. A marginal risk for severe weather remains in place, with isolated damaging wind gusts and a brief, weak tornado possible this afternoon and evening.
The most active window runs from 11 a.m. to 8 p.m., when heavier downpours may reduce visibility and cause ponding on I-77, SC-277 and US-1. Urban and poor-drainage areas in Columbia, West Columbia and Cayce could see minor flooding during peak rainfall.
Motorists should avoid driving through water-covered roads and allow extra stopping distance during heavier showers. Residents are urged to secure loose outdoor items and ensure they have multiple ways to receive warnings in case a severe thunderstorm or tornado warning is issued.
Rain tapers off late Sunday night into early Monday, but additional advisories could be issued if storms intensify or localized flooding develops before the system exits the region.
