COLORADO, USA — There's little doubt that this week's epic blizzard, known as a 'bomb cyclone', left its mark on Colorado. 

It brought snow and extremely strong wind gusts, which impacted travel both on the roads and in the air. Those winds brought trees and damaged powers lines, leaving thousands of people in the dark.

Here's a look at some at its impact by the numbers:

FATALITIES

A member of the Colorado State Patrol was struck and killed by a vehicle on Interstate 76 on Wednesday morning. 

Cpl. Daniel Groves, 52, was outside of his patrol car on the highway near Roggen helping a vehicle that had slid off the road when he was hit by another driver who lost control of his car, CSP said.

AIRPORT IMPACT

On Wednesday, more than 1,400 flights in and out of Denver International Airport were canceled. Around 12:30 p.m. that afternoon, the airport closed all six of its runways due to extremely low visibility on the airfield. It is only the fourth time in the airport's history that all runways were closed.

Four of the six runways reopened early Thursday, but the first flight didn't leave until just after 8 a.m. It wasn't until about 6 p.m. Thursday when the remaining two runways finally opened, according to a tweet from the airport.

RECORD BREAKING

The National Weather Service has yet to officially confirm that a Barometric pressure reading of 970.4 mb recorded in Lamar on March 13 is the lowest reading ever recorded in the state.

The previous record is 975.8, however, the NWS said it was working with the Colorado Climate Center, the Weather Prediction Center and the National Center for Environmental Information before calling it an official record.

In a tweet, the Weather Prediction Center shared an image that showed that pressure hit an all-time low for the month of March 

Wednesday’s barometric pressure in Colorado, meanwhile, was similar to a category 2 hurricane.

A “bomb cyclone” is defined by a drop in barometric pressure that exceeds 24 millibars in 24 hours.
