Storm To Hit Rockies Before Forming New "Bomb Cyclone"

HELENA, Mont. (AP) — Flood, snow, avalanche and fire alerts popped up Monday from Idaho to Colorado, as parts of the U.S. interior that were paralyzed by blizzards and floods last month braced for round two of an unusual weather phenomenon.

Welcome to springtime in the Rockies and parts of the Great Plains.

It’s not unusual for floods, snow and fire to co-exist in the Rockies thanks to powerful storms blowing through the mountains, melting snow swelling waterways and high winds sweeping across dry grasslands and trees that haven’t seen their first green shoots and leaves.

But what is unusual is what’s coming next. A storm system that is moving in from the Pacific Ocean is forecast to intensify and form into a new inland “bomb cyclone.”

A bomb cyclone is a rapid drop in air pressure — at least 24 millibars in 24 hours — and often is over or near oceans or seas because it requires warm moist air smacking into cold dry air, along with volatile weather from the jet stream. The central and mountain part of the country may get one of these every few winters, said Greg Carbin, forecast branch chief for the National Weather Service’s Weather Prediction Center in Maryland.

But this would be the second such storm in less than a month. The March 13 storm caused massive flooding in the Midwest, a blizzard in Colorado and Wyoming, and produced winds of between 96 mph and 110 mph (155 and 177.02 kph).


This week’s bomb cyclone one is expected to be similar in intensity and in snowfall, meteorologists said. Heavy, wet snow will fall from the Nebraska panhandle through south central and southeastern South Dakota into western Minnesota. Wind speeds can reach 50 mph to 60 mph (80 to 96 kph) across Kansas.

“This blizzard will further exacerbate flooding in Nebraska with the added insult of heavy snowfall to eventually melt,” said Ryan Maue, a meteorologist at the private weathermodels.com. “This is more bad news for suffering farmers who are unable to flip the calendar on winter.”

But first, the storm is expected to flooding in Idaho and western Montana, and dump up to 2 feet (61 centimeters) feet of snow in the mountains of Montana and Wyoming as it moves in from the Pacific Ocean. Parts of Colorado that were under a fire warning Monday are expected to see snow and temperatures drops of more than 40 degrees by Wednesday at the southern edge of the storm, meteorologists said.

3. Divine judgement.

Then some children were brought to Him so that He might lay His hands on them and pray; and the disciples rebuked them.

But Jesus said, "Let the children alone, and do not hinder them from coming to Me; for the kingdom of heaven belongs to such as these."

Mark 19: 13-14
