What is a flash flood?
A flash flood is a flood caused by heavy or excessive rainfall in a short period of time, generally less than 6 hours, according to the NWS. Flash floods are usually characterized by raging torrents after heavy rains. A flash flood can be sudden and violent and take just minutes to develop. It is possible to experience a flash flood in areas not immediately receiving rain.
What’s the difference between a flash flood watch and a flash flood warning?
A flash flood warning is issued when a flood is imminent or occurring, the NWS says. If you are in a flood prone area, you should move immediately to high ground.The NWS issues a flash flood watch when flash flooding is possible.
What to do during a flood warning
- If advised to evacuate, do so immediately.
- Use a battery-operated radio or television to get the latest emergency information.
- Do not walk through floodwater. Just six inches of floodwater can sweep you off your feet if it is moving swiftly.
- Turn around, don’t drown; do not drive into a flooded street. Cars can be swept away by two feet of moving water or there may be unseen damage to the road. If you come to a flooded area turn around and go another way. Most flood-related deaths are caused by people driving through water.
- Watch out for fire hazards.
- Move to higher ground.
- Stay alert, turn weather notifications on.
- Do not allow children to play in flowing water. Waters can hide rocks, trees and debris.

Monday is a First Alert Weather Day in Colorado as strong winds and very dry air create critical fire weather conditions.
The National Weather Service has issued a Red Flag Warning through this evening for the I-25 Corridor, the Front Range Foothills, and much of the northeast plains. Wind gusts between 45 and 55 mph will be common, with some foothill areas briefly seeing gusts as high as 70 mph. The strong winds are also causing patchy blowing dust on the plains, reducing visibility at times.
In the mountains, a quick burst of snow moved through early Monday morning, along and north of the I-70 corridor. Conditions are expected to improve by midday as drier air moves in.
Winds will ease later this afternoon and evening, setting the stage for a Freeze Warning overnight for parts of the I-25 corridor and adjacent plains.
Tuesday brings calmer weather and more seasonal temperatures in the 60s.
Police are investigating after a small plane crashed Sunday afternoon near the runway at the Erie Municipal Airport in Weld County, according to the department.
The Erie Police Department first posted about the single-plane crash at 3:59 p.m. Sunday. Department spokesperson Amber Luttrell said the crash happened about 15 minutes before that.
Two people were on board the plane, Luttrell said. The extent of their injuries was not immediately available.
Additional information about the crash, including the cause and the plane’s flight information, was not immediately available Sunday.
The Federal Aviation Administration and the National Transportation Safety Board will investigate the crash, Luttrell said.
Neither agency immediately responded to requests for comment on Sunday.
