Tropical Storm Arthur, the first named storm of the 2026 Atlantic hurricane season, has formed off the middle Texas coast with 45 mph winds – but forecasters say its greatest threat will come from torrential rain and flash flooding rather than wind.
The storm developed on Wednesday morning, 17 June, with maximum sustained winds just six mph above the threshold for tropical storm status. It is expected to weaken quickly once it moves inland, but forecasters warn the rain, not the wind, is the real danger. Behind it, a clash of air masses is raising the odds of tornadoes from the Texas coast through the Deep South.
