Debby Deluge Continues; But Slingshot North Caps Totals, Weekend Salvaged!

Crawls and stalls before rapid acceleration north

1. Update on Track, Timing and Totals

3. Special Requests

Good morning atmospheric audience. How’d everyone fair the other day across the tri-state including parts of NJ, NYC, Long Island, lower Hudson Valley? What took place was called a Predecessor Rainfall Event (PRE) which is when moisture builds along a stationary boundary far from a tropical system. Check out some of these rainfall totals!

Let’s get right to it. As of the latest 8am NHC update, Debby, made landfall near Bulls Bay, SC at 2am with current sustained winds of 50mph and minimum pressure of 995mb. It’s currently located approximately 65 WNW of Myrtle Beach, SC, still spinning and crawling NW at 5mph. It’ll meander over SC still deluging the SE coast with flooding downpours. See some the rainfall totals below over the past 72 hours. which will certainly climb over the day.

Here’s the good news. Dry air has weakened Debby’s inner core, which prevented strengthening. Also, once the trough moving SE from the Great Lakes picks up Debby it’ll rapidly accelerate due North (and become post tropical) to our neck of the woods Friday into early Saturday, yet further west then initially thought. What’s this mean?

It’s track heads North to VA, DC, NJ (west of I95) later Friday, rides the spine of Rt 87 to the Adirondacks, then steers Northeast and swipes New England before jumping offshore and out to sea Saturday afternoon. The bulk of the rainfall totals will be in central PA, and west of I87 (2-5″), 2-4″ in VT, and 1-3″ across NH, ME, along with western CT and MA.

The I95 corridor from Cape May to Rumson, up to Bellmore over to Clinton, to the Cape into Beantown will range from 1-2″, but will receive some of the stronger gusts (which you usually see on the east side of tropical systems) from 35mph-55mph. Can’t rule out some gusts up to 60mph, especially on the tip of LI and the Cape. Don’t get me wrong, it’ll be gusty across the entire region (also in higher elevations of ADK, VT and NH) and won’t take much to knock down trees due to the very saturated grounds.

There is a chance of isolated tornados. I’ll be posting on warned cells on Twitter through out the storm so turn on your notifications if you follow me. If you don’t have X, get it and just @weatherremarks for up to the minute alerts. It’ll feel very humid and tropical outside starting early Friday, trust me. Here’s a look an the approxmate time stamps below on timing:

RequestRemarks

For my friends up in Chittenden, VT for your wedding Saturday, you certainly dodged a devastating deluge. While VT doesn’t need another 2-4″ and strong winds given the past 2 July horrible floods, rainfall should be over by daybreak with sunny skies breaking out (very windy) with temps in the mid 70s! If folks are driving up Friday, I’d strongly recommend getting up there late morning / early afternoon the latest. Congrats! GAM’s CO-OP Saturday pool party in Mt. Kisco should also be a go under sunny skies, and breezy conditions. For my long time follower (and huge supporter), Debby will be ahead of you on the SC to DC trek Fri. The later you leave the better. Plus you may want to take 77 to 84 vs 95 to avoid major flooding on the eastern part of trip (heads-up for isolated yet major feeder bands). I teed up a stunning sunny stretch at Cape May, enjoy. For my 2 favorites, clear skies are in order for the Beantown cruise and trip the Cape on Saturday!

That’s it for now! Again, while we got lucky (this time) plenty of flash flooding, strong possibility of down trees, wires and power outages, so don’t be caught off guard. Enjoy the stunning latter half of the weekend, especially the rather tranquil cooler than normal temps I mentioned last Sunday. However, while the Atlantic has been especially quiet, with the exception of Debby and Beryl, buckle up folks. By the middle to end of next week, we’ll have another threat lurking in the Caribbean and staring down the East Coast and Gulf. This will be an active season. Besides Florida and gulf the usual targets, the Northeast / New England drought may be ending. Stayed tuned. With that being said, remember, weather and I never sleep!
