Flash Flood
In short
Texas is currently under a level 2 of 4 flash-flood threat for the Halloween weekend, as reported on 31 October 2026.
What is happening
Tropical Storm Vance is bringing deep moisture to Texas, making flooding very likely in some areas. Meanwhile, recent severe storms in the Phoenix area have trapped drivers in vehicles on flooded roads.
When
The Texas threat is active for the Halloween weekend of 31 October 2026; Kenya Met warns of rain in 41 counties over five days starting 30 October 2026.
Why it matters
Flash floods are dangerous because they occur in fewer than six hours, often catching people by surprise. They can wash out roads, strand vehicles, and cause rapid damage to low-lying areas.
Easy to mix up
Flash floods are distinguished from regular floods by their rapid onset, typically occurring within six hours of rainfall.
