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.

Suddenly hazy skies in Denver prompt some residents concerned about wildfire smoke to call 911

Suddenly hazy skies in Denver prompt some residents concerned about wildfire smoke to call 911

Some people who live in the Denver metro area on Thursday afternoon were making calls to 911 after skies became noticeably hazy and winds kicked up. It was due to smoke from wildfires in Nebraska moving into Colorado. A cold front also was moving through the Front Range, and there is dust in the air.

The poor air conditions led to reduced visibility downtown after 3 p.m. Several of CBS Colorado’s City Cams showed dust or smoke in the air.

Temperatures were expected to drop by as much as 20 to 30 degrees with the cold front.

The suddenly dusty skies prompted at least one fire agency to put out a plea to residents to please only call 911 “if you see flames.” That warning was put out by South Metro Fire Rescue, which shared a photo on X of an office building with haze visible outside.

South Metro Fire Rescue said in their post that the smoke is from Colorado’s neighbor to the east. They called it a “significant haze” in the air.

Earlier this month, the Morrill Fire and the Cottonwood Fire burned a significant amount of Nebraska grassland and ranchland. They have mostly been contained by firefighters. Nebraska Gov. Jim Pillen said those two fires combined with several others have burned approximately 800,000 acres of land. On Thursday, Pillen announced that he is signing several executive actions intended to ease the burden caused by the fires.

There were no wildfires burning in the Denver metro area on Thursday afternoon.

Colorado homicide suspect wanted in fentanyl-related death arrested in Colombia

ARAPAHOE COUNTY, Colo. (KKTV) – A homicide suspect based out of Colorado, wanted in a fentanyl-related death, is back in the state after being captured in Colombia.

The Arapahoe County Sheriff’s Office (ACSO) said 33-year-old Max Arsenault had been on the run since January 17.

Deputies said this stemmed from an incident in May 2023, where deputies responded to a call for a man named Nicholas Dorotik, who was found unresponsive.

ACSO said the cause of death was a mixed drug overdose involving meth and fentanyl, having about three times the lethal amount of fentanyl in his system.

One year later, Arsenault was arrested. He was scheduled for trial in January 2026 when deputies said he fled the country while on bond three days before the trial was set to start.

He was caught in Medellin, Colombia, on March 4, following a two-month international investigation. He has since been extradited back to Denver, where he is facing charges and awaiting trial.
