The U.S. East Coast is currently experiencing a volatile weather pattern characterized by rainy, windy conditions, and the potential development of a bomb cyclone. Western Maine, in particular, is expected to face freezing rain, heavy downpours, unusually high temperatures, and damaging winds within a short timeframe. The National Weather Service forecasts that these adverse weather conditions will persist until Wednesday night, with the possibility of flooding in certain areas.
The impending storm is being fueled by an atmospheric river, a long band of water vapor that can transport moisture from tropical regions to more northern areas. This atmospheric phenomenon is expected to draw moisture from the Atlantic Ocean off the U.S. Southeast coast and transport it to states like Maine. Meteorologists are anticipating a 'multifaceted storm' that could bring two to three inches of rainfall to some regions.
The Northeast region experienced a mix of fog and light freezing rain on Tuesday night, transitioning into Wednesday. As temperatures rise into the 50s Fahrenheit, there is a concern for flash flooding and rapid rises in stream levels. Additionally, the storm has the potential to undergo bombogenesis, a process where a cyclone rapidly intensifies, leading to severe rainfall.
Preparations for the inclement weather are underway in various states. The Mount Washington Avalanche Center in New Hampshire issued a special bulletin for the Presidential Range mountains due to significant snowfall in recent weeks. The center warned of potential avalanche risks and unsafe conditions for outdoor activities such as stream crossings, skiing, and hiking trails.
In Vermont, a flood watch is in effect from Wednesday afternoon to Thursday morning, with the city of Montpelier advising residents to take precautions against mild flooding. Ski resorts across the Northeast are bracing for challenging conditions, with some recommending visitors to equip themselves with appropriate gear for wet weather.
