A Strong winter storm This week is expected to bring heavy snow and freezing temperatures to the majority of the United States. snarling holiday travel plans Officials are advising citizens to be vigilant. The storm could cause severe flooding to millions of Americans.

Google searches for the term bomb cyclone, a weather phenomenon also known as a bomb storm, spike whenever it is mentioned by meteorologists. We are seeing the same trend this week.

Here’s a quick overview of what you need to know.

What is a bomb-cyclone?

A bomb cyclone refers to a rapidly-developing storm when atmospheric pressure drops below 24 millibars in 24 hours, according to the National Oceanic and Atmospheric AdministrationOnline notes.

A bomb cyclone is a situation in which the atmospheric pressure at its center drops rapidly. To qualify, the pressure must drop to 1 [millibar]John Moore, a meteorologist and public affairs specialist for the National Weather Service, said that he received at least one hour of data every hour over a 24-hour period.

NOAA explains that this can occur when a cold mass collides with warm mass such as air over warm ocean water.

It is called a bomb cyclone.

According to Mike Bettes (a meteorologist for The Weather Channel), the nickname bomb cyclone was invented in the 1940s.

“It’s called bomb cyclone because low pressure (or cyclones) undergoes “bombogenesis,” which refers to how quickly the low pressure develops,” Bettes explained to CBS News.

What are the effects on a bomb cyclone

Bomb cyclones can pose multiple hazards and the severity of each one will depend on where it is located and how fast it moves. The intense pressure can cause heavy winds, blizzard conditions, heavy snow that can reduce visibility, and rain. According to the agency. Coastal flooding can also be caused by heavy precipitation.

“In winter, you can have extreme snowfall and wind gusts. This can lead to dangerous travel conditions, including blowing and drifting snow, poor visibility, and hazardous weather. Airlines will cancel flights when the conditions are too dangerous to fly. Bettes stated that high winds can often cause widespread power outages.

Combining cold temperatures with strong winds can lead to dangerous wind chills that can increase the risk of frostbite.

Moore stated that a bomb cyclone could also have a ripple effect on other weather events.

“Some bomb cyclones can cause temperature drops to be very sharp along the frontal border. Moore pointed out that there can also be storms in the warm sector of a storm along the frontal border.

When do bomb cyclones occur most often?

Bomb cyclones can occur at any time of the year, but they are more common in winter months. According to a report, they are most common between December and early March.2017 study from Journal of Applied Meteorology and ClimatologyThis study analyzed the patterns and effects of bomb cyclones on the northern Pacific Ocean between 2000 and 2015.

Moore said the same thing today.

He agreed that bomb cyclones are more common during the cold season.

How to prepare for a bomb storm

You should be prepared for any storm that may hit your area.

Keep up-to-date with the weather forecast in your area, make sure you have enough supplies for a few days, and ensure that your home is safe.

“If you expect impacts similar to a winter thunderstorm, prepare accordingly. If you live in a coastal area, coastal flooding can have an impact. Moore stated that heavy rainfall from a bomb cyclone can also cause flooding. People who live near areas where flooding is possible should be aware.

Moore’s advice was repeated by Bettes, who encouraged those in direct danger of a bomb storm to stay home.

“In the event that there is a power outage, people should only use the generator as directed in the instruction manual. Never operate a generator indoors.” He suggested that you also consider having a backup heat source, which doesn’t involve an open flame.
