Severe Thunderstorms and Flood Risks Sweep Across Texas, the Mid-Atlantic, and the Northeast (June 12-14, 2026)

Event Overview
A coordinated series of severe thunderstorms, strong winds, hail, and flash-flood threats struck Texas, Pennsylvania, Delaware, and New Jersey from June 12 to June 14, 2026, as an unseasonal cold front intersected lingering moisture from Tropical Storm Christina and a tropical disturbance over Mexico. The storm system also produced isolated tornadoes in Pennsylvania.
Key Hazards
Wind gusts reached 60 mph in Texas, Pennsylvania, and Delaware; hail up to 1 inch fell in the Rio Grande area and 0.75 inch in Sussex County, Delaware; rainfall topped 5 inches in Waco, Texas, while the Lehigh Valley expected 0.25-0.5 inch. New Jersey’s coastal flood advisory warned of up to 1 ft of tidal inundation.

Official Guidance
National Weather Service advisories urged people to move to interior rooms on the lowest floor, avoid driving through water, and stay indoors. TxDOT reported flooded waterways in El Paso’s Upper Valley and issued flash-flood alerts for Socorro. KFOX14 advised securing loose objects and checking updates via its “Chime In” service. New Jersey officials recommended moving vehicles to higher ground.
Local Impacts
El Paso’s Sunset neighborhood reported water-covered intersections; I-35 near Waco closed after more than five inches of rain fell within hours. Flash-flood warnings in central Texas prompted emergency-services alerts for motorists.
Conflicting Accounts
Some sources attribute the severe weather primarily to the advancing cold front, while others highlight tropical moisture from Christina and the Mexican disturbance as the dominant factor; rainfall totals for many counties remain unverified.
