US EditionForecast Models Are Predicting a Bomb Cyclone Off the East Coast This Weekend
A rapidly intensifying coastal low could bring heavy snow, strong winds, and coastal flooding to the East Coast, with forecasts expected to clarify by Thursday evening.
- This weekend, forecasters are tracking a rapidly intensifying coastal low that StormTeam 5 described as a bomb cyclone expected to deepen Sunday into Monday off the East Coast.
- Model output shows a rapid pressure collapse, with pressure dropping from about 1004 millibars Saturday to 971 millibars 24 hours later, fueled by cold air supply, available moisture, and a full moon with higher-than-normal astronomical tides.
- Model guidance shows a split, with the European/ECMWF model holding the low offshore while the GFS model keeps it closer to the coast, producing three primary track solutions including the benchmark 4070 offshore reference.
- If the track is close to shore, coastal communities in Southern New England and the tri-state area could face heavy snow, damaging winds with gusts of 40 and 50 miles per hour, and high astronomical tides impacting Sunday and Monday.
- Forecasters caution that confidence remains low and forecasts may change, expecting clearer guidance by Thursday while monitoring three possible tracks over the next few days.
