What is it?
- It is a mid-latitude cyclone that intensifies rapidly.
- It has low pressure at its center, weather fronts and an array of associated weather, from blizzards to severe thunderstorms to heavy precipitation.
Reasons for the Formation
- Storms form when a mass of low-pressure air (warm air mass) meets a high-pressure mass (cold air mass).
- It occurs when a midlatitude cyclone rapidly intensifies, dropping at least 24 millibars over 24 hours.
- the pressure difference, or gradient, between the two air masses, therefore making the winds stronger.
Impacts
- Heavy accumulation snow
- Storm Surge
- Coastal Flooding
- Wind Damage
- Breach Erosion
- Thunderstorm
- Heavy Precipitation
