Saturday Night Update: October 1 2022
Ian is no longer a tropical system, but it may have a second life as a NEW nor’easter forming in a few days off the Mid Atlantic US. The circulation hammered Florida as the 5th strongest landfalling hurricane on record and may turn out to be the costliest disaster on record. While heavy rain is the status tonight, the next phase may lead to additional beach erosion for Maryland, Delaware, and the entire Mid Atlantic in the days ahead.
Saturday Night Set Up
Low Pressure in south central Virginia is the remains of Hurricane Ian’s eye. We often call these remnant circulations the ‘ghost of’ to maintain that name integrity as we follow it well after it lost topical characteristics.
We can see the spin seemingly stuck over Virginia and West Virginia. It will begin to shift east Sunday. With some help from a cool pocket of air in the jet stream and gradient with warm water off the east coast, this will develop into a NEW STORM off the Mid Atlantic coast.
Let’s jump to what it may look like, then back up and watch the maps in motion to show how it will evolve.
Jet Stream:
This cool pocket of air aloft is cut off from the main jet stream. This will slowly wander to the coast between Sunday and Tuesday while keeping our region chilly, unsettled, and wet.
Snow Lovers: If this pattern repeats in winter, it would very beneficial to snow outlooks. I am storing this in my Atmospheric Memory File and maintaining Faith in the Flakes (#FITF).
This is where we will watch the developing Low spin up quickly. See the animation below.
Note: The Upper Low above and the Surface Low are nearly stacked. That is a recipe for quick development over the warmer water, just not tropical. It will be like a Nor’easter.

October 3 Ian Nor’easter: Rain And Wind Advisories: New Beach Flood Video From Ocean City
This shows the circulation at the surface.
This will increase Sunday evening through Tuesday.
The stronger winds will be across Delmarva and along the coast…
Steady winds will be from the North and Northeast. This will keep our temps cool, and drain water out of the Chesapeake Bay. The tide cycles will get lower…
Beaches on the ocean side will experience a few more days of pounding waves and erosion.
This is mainly Delmarva and the coastline. But stay tuned for any further expansion inland.
This is the GFS Model, and I know there will be some variation among the guidance with this next phase of the event. I will show the contrast tomorrow. This is simply for an idea of what could fall for flood prone areas around the Chesapeake Bay and Delmarva.
