Flood Watch For Coastal Storm Sunday Afternoon and Overnight
December 16 2023
Saturday Night Update
The storm we have talked about for a few days has now taken form. An organized Low Pressure is off the west coast of Florida and will spread north up the East Coast on Sunday.
This event will bring multiple weather concerns for our region:
- Flooding From Rain: 2 to 3+ inches are possible for many areas.
- Flooding From High Water: Winds will pile water higher on the WEST SIDE of the Chesapeake Bay and the Atlantic coast.
- Wind Gusts: Sunday night will bring 40+ mph for central Maryland and up to 60 mph by the ocean coast.
Flood Watch Sunday
Saturday Night Set Up
Low Pressure is located just west of Tampa, FL. This is continuing to develop and will move to the Northeast as it grows stronger.

RESTATING MY MESSAGE ABOUT DYSLEXIA
I am aware there are some spelling and grammar typos and occasional other glitches. I take responsibility for my mistakes and even the computer glitches I may miss. I have made a few public statements over the years, but if you are new here, you may have missed it: I have dyslexia and found out during my second year at Cornell University. It didn’t stop me from getting my meteorology degree and being the first to get the AMS CBM in the Baltimore/Washington region. One of my professors told me that I had made it that far without knowing and to not let it be a crutch going forward. That was Mark Wysocki, and he was absolutely correct! I do miss my mistakes in my own proofreading. The autocorrect spell check on my computer sometimes does an injustice to make it worse. I also can make mistakes in forecasting. No one is perfect at predicting the future. All of the maps and information are accurate. The ‘wordy’ stuff can get sticky. There has been no editor who can check my work when I need it and have it ready to send out in a newsworthy timeline. Barbara Werner is a member of the web team that helps me maintain this site. She has taken it upon herself to edit typos when she is available. That could be AFTER you read this. I accept this and perhaps proves what you read is really from me… It’s part of my charm.
