Weather Tidbits: Nor’easter Types

This Weather Tidbits explain what is a nor’easter and it’s two types of formation. A nor’easter is a mid-latitude cyclone that develops or intensify off the eastern seaboard of North America; moves northeastward along the coast. The name nor’easter is due to northeasterly winds battering the coast. Nor’easter are most frequent & violent between September & April. These storms are capable of producing blizzards, heavy rain or snow, ice, severe weather, hurricane force winds & coastal flooding. Nor’easter form in two ways, Miller A & Miller B.

Miller A is your common setup where the low typically develops in the Gulf of Mexico or along the southeast coast along an old front. The storm will intensify rapidly as it moves up the coastline with the Mid-Atlantic and New England states usually hit hardest. Icy conditions can occur as far south as Georgia & the Carolinas; while severe weather is also possible in Florida. A Miller B storm originates as an area of low pressure over the Midwest then moves east. The low weakens as it hits the Appalachian Mountains; however another low forms on the east side of the mountains, close to the coastline. The warmer gulf stream water helps it intensify as it turns northward; which brings heavy snow for New England & Mid-Atlantic.
