Record Rain, Life-Threatening Flooding — and Oklahoma’s Night Isn’t Over

Oklahoma City —

Record rain turned into life-threatening flash flooding across Oklahoma City on Wednesday — and with severe storms still possible tonight, the night ahead looked almost as dangerous as the day behind it. Some weather days announce themselves. This one just kept raining until the records gave up.

Slow-moving thunderstorms parked over Oklahoma on Wednesday and unloaded. By the time most of Oklahoma City was thinking about a second cup of coffee, the city had already broken its daily rainfall record — not edged past it, beaten it by more than an inch, according to the National Weather Service office in Norman. And the cruelest part of the forecast is the simplest: as of Wednesday evening, it still was not done.

A record before lunch

The numbers, gathered by The Oklahoman and by The Watchers in its summary of the National Weather Service reporting, tell the story of a genuinely exceptional rain event. Gauges in Oklahoma City recorded 4 to 5 inches by morning. Across the metro, between 3 and 6 inches fell, producing what the Weather Service described as widespread, life-threatening flash flooding.

West of the city, it was worse. Up to 9 inches fell in western Oklahoma. Radar-indicated totals reached 4 to 11 inches in parts of Canadian, Kingfisher, Blaine and Caddo counties — the kind of totals that do not drain politely, because there is nowhere for that much water to go that fast.

The Weather Service said that by 10 a.m., Oklahoma City had beaten its daily rainfall record by over an inch, and that it was the most rain the city had seen in more than two years. Records like that, broken before mid-morning with hours of rain still in the forecast, are the ones forecasters remember.

Warnings across the metro

Flash Flood Warnings covered Oklahoma, Canadian, Cleveland, Kingfisher and Logan counties during the day, and the Weather Service classified the damage threat in its warning language as “considerable” — a word the agency does not use casually. Flash flooding of creeks and streams, urban areas, highways, streets and underpasses was reported across the metro, exactly the mix that makes these events dangerous: not one river in one place, but water in a hundred ordinary places people drive through without thinking.

The rivers are part of the story now, too. Major flooding was forecast on the Canadian River near Bridgeport. Weather.com’s alert listings for Oklahoma City carried River Flood Warnings and a Flood Watch running until Thursday at 1 p.m. CDT, along with heavy thunderstorms expected Wednesday night. The Weather Prediction Center placed Oklahoma into the Red River Valley of Texas under a Moderate Risk of excessive rainfall through 12:00 UTC on Oct. 15 — the second-highest category on its excessive-rainfall scale.

Tonight: severe storms on top of floodwater

Here is where Wednesday evening gets complicated. In its Wednesday afternoon forecast discussion, the Weather Service warned that storms could strengthen late Wednesday evening along and north of Interstate 44, bringing damaging wind, hail and a possible tornado, helped by low-level wind shear. In other words, the same saturated state that spent the day flooding could spend the night dealing with severe thunderstorms of a more classic, violent Oklahoma kind.

And the rain itself may not be finished. Forecasters said another 4 to 6 inches could fall in a narrow corridor by Thursday morning. On dry ground, that would be a flood threat. On ground that has already taken 4, 6, in places 9 or more inches, it is a threat stacked directly on top of an emergency already in progress. Creeks are full, rivers are rising, and the soil has nothing left to absorb.

Behind all of it, a cold front is waiting. Once it pushes through, daytime highs are expected to drop into the 50s and 60s — a sharp, gray exhale after the storm. Thursday will feel like a different season. Getting to Thursday is the work of tonight.

The one rule that matters tonight

Every flood-safety message from the National Weather Service comes back to the same plain instruction, repeated so often because it keeps being true: turn around, don’t drown. Most flood deaths in the United States happen in vehicles, in water that looked shallow, on roads people had driven a hundred times. Floodwater over a roadway hides everything that matters — the depth, the current, and whether the road underneath is even still there.

So, for anyone in central Oklahoma reading this tonight: do not drive through flooded streets or underpasses, do not cross low-water crossings that are running high, keep phones charged and weather alerts on, and check on neighbors, especially anyone who lives near a creek or in a low-lying spot. If water is rising around your home, move to higher ground early rather than late.

Radio Oklahoma News and other local outlets continued tracking warnings through the day as county after county was added, and the warning map will keep changing overnight. Local radio, the Weather Service in Norman, and county emergency management remain the fastest sources for street-level detail.

We will keep following this in our news coverage as the night develops, and you can find the rest of the evening’s headlines there as well. Oklahoma has had harder weather days in its history, but a record broken by 10 a.m., a metro under life-threatening flood warnings, and a severe-storm threat still to come after dark — that is a full day by any measure, and it is not over yet.
