Flood watch and flash warnings hit Northeast Ohio Sunday
The National Weather Service issued Flash Flood Warnings for Ashland and Richland counties and a Flood Watch across much of Northeast Ohio through 10 p.m. on Sunday, July 5, 2026, as slow-moving showers and thunderstorms threatened communities from Cleveland to Erie County, including Kelleys Island, with rainfall rates of 2 to 3 inches per hour. Holiday weekend storms shifted the region's focus from fireworks to flood safety as forecasters warned that flash flooding caused by excessive rainfall was possible across multiple counties.
Key Takeaways
- Flash Flood Warnings were in effect for Ashland and Richland counties until 10:30 p.m. Sunday, with a broader Flood Watch across 11 Northeast Ohio counties until 10 p.m.
- Peak rainfall rates of 2 to 3 inches per hour were expected where the strongest storms persisted, raising risk for creeks, streets, and poor drainage areas.
- Flood Advisories also covered Erie, Huron, and Lorain counties — the Erie County zone includes Kelleys Island and other Lake Erie shoreline communities.
- 19 First Alert Weather warned that slow-moving low pressure would keep humid, stormy conditions in place through Tuesday with more rain likely Monday.
- FOX 8 News reported spotty storms lingering Sunday night and scattered downpours returning Monday afternoon.
Which Northeast Ohio counties are under flood alerts?
According to WKYC, the NWS placed Ashland and Richland counties under a Flash Flood Warning through 10:30 p.m. Sunday. A separate Flood Watch covered Ashland, Cuyahoga, Holmes, Huron, Mahoning, Medina, Portage, Richland, Stark, Summit, and Wayne counties until 10 p.m.
Additional Flood Advisories were active for Erie, Huron, and Lorain counties until 3 p.m.; Geauga, Portage, and Summit until 5 p.m.; and Mahoning and Trumbull until 6 p.m. For residents on Kelleys Island and along the Lake Erie shore in Erie County, those advisories signaled that even moderate runoff could flood low-lying roads and basements quickly.
Why is heavy rain causing flash flooding in the region?
The NWS said showers and thunderstorms would slowly move east to southeast across the Cleveland area through Sunday evening. Forecasters warned that excessive runoff could flood rivers, creeks, streams, and other low-lying, flood-prone locations.
Cleveland 19's First Alert Weather team attributed the pattern to a slow-moving, broad area of low pressure parked over Northeast Ohio through Tuesday. Thunderstorms were expected to remain slow-moving, producing locally very heavy rain rather than quick passing showers.
FOX 8 reported that storms during the holiday weekend had already prompted Severe Thunderstorm Warnings and Tornado Warnings, with locally heavy rain and reported wind damage in Mahoning County from a tornado-warned storm the NWS had not yet confirmed as a tornado or straight-line wind.
What should residents do during a flood watch or warning?
A Flood Watch means conditions are favorable for flooding — it does not guarantee flooding will occur, but residents should stay alert. A Flash Flood Warning means flash flooding is imminent or already happening; people in flood-prone areas should move to higher ground immediately.
The National Weather Service flood safety page urges drivers to turn around rather than drive through flooded roads, since most flood deaths happen in vehicles. With humid overnight lows in the upper 60s and more rain in the forecast, keeping phones charged and monitoring local alerts matters — especially on isolated lake communities like Kelleys Island where drainage can lag behind mainland forecasts.
What is the forecast for Monday and the week ahead?
FOX 8 projected that storm intensity would decrease Sunday evening as daytime heating faded, leaving spotty wet weather overnight. Monday brings another round of scattered to numerous showers, downpours, and storms, with coverage peaking in the afternoon and highs around 80 degrees.
19 First Alert Weather expected humid conditions Monday with scattered thunderstorms and isolated showers Tuesday, with afternoon highs near 80. FOX 8 noted the week should feel cooler than last week's heat wave, with highs generally in the lower to mid 80s before a brief temperature spike Thursday and more storms as a cold front moves through Thursday and Friday.
As communities dig out from standing water, understanding how forecasting and emerging technology shape severe-weather response continues to matter for every county on the alert map — from urban Cuyahoga to lakefront Kelleys Island.
