North Carolina Faces Flash Flood Threat Ahead of Extreme Heat Wave

The National Weather Service issued a Flash Flood Warning for parts of central North Carolina, covering northeastern Harnett, southern Johnston, southwestern Wake and central Wayne counties, effective until 2:30 a.m. EDT. Heavy thunderstorms have already dropped 2–5 inches of rain near Smithfield, with an additional 1–3 inches possible. Officials warned of life‑threatening flash flooding, especially south of Highway 64, where drainage systems could be overwhelmed, low‑lying roads flooded, and strong wind gusts may fell tree limbs.

Travel on Interstate 40, Interstate 440, U.S. 70, U.S. 1 and nearby secondary roads around Raleigh, Smithfield, Goldsboro, Dunn and Benson could deteriorate rapidly. Authorities urged motorists not to drive through flooded roadways, noting most flood‑related deaths occur in vehicles.

Meteorologists also warned that the region will shift from flood concerns to dangerous summer heat later in the week. A high‑pressure system is expected to push temperatures toward 100 °F (38 °C) by Wednesday‑Friday, raising health risks for vulnerable populations. Residents were advised to stay informed, avoid flooded areas, and prepare for the upcoming heat wave.
