Weird weather on tap – coast-to-coast, border-to-border ‘bomb cyclone’ set to bring snow, hail and rain
| Wed March 13, 2019
CNN – An intense and ferocious winter storm — a “bomb cyclone” — is expected to bring hurricane-force wind gusts, blizzard conditions and a flood threat across a swath of the US heartland Wednesday.
A bomb cyclone occurs when there is a rapid pressure drop, falling at least 24 millibars (which measures atmospheric pressure) over 24 hours known as bombogenesis.
The massive storm is expected to wallop areas including the Rockies, Central/Northern Plains to the Upper Midwest with blizzard conditions and winds that could blow from 50 to 70 miles per hour.
Other hazards include heavy snow and severe storms with possible tornadoes and flooding.
Blizzard and winter storm warnings are in effect for portions of Colorado, Wyoming, Nebraska and South Dakota. Heavy snow is expected in portions of the Rockies and northern Plains, including Denver into Thursday.
Travel will be dangerous, if not impossible, at times, across the front range where the blizzard warning has been issued.
Severe storms capable of producing damaging winds, hail, and tornadoes is forecast from the southern Plains and into the Mississippi River Valley.
More than 45 people million are under a high wind threat; more than 10 million are under winter storm threats; and more than 15 million are under a flood threat.
The National Weather Service in Boulder, Colorado, issued a blunt message Tuesday:
“Please cancel any travel plans Wednesday afternoon and evening especially east of I-25, and stay tuned for further updates!”
It warned of icy roads, whiteout conditions and strong winds.
“The heavy snow and visibility near zero will create extremely dangerous travel conditions, and power outages are also possible,” according to the National Weather Service.
