ISAIAS RACING NORTHEAST CREATES TIMING ADJUSTMENTS
Good morning everyone. Tropical Storm Isaias has accelerated even faster than we originally forecasted, which means a major adjustment to the timing. Other than that, everything is unfolding as expected, with he heaviest and most prolonged rain, off to our west.
SATELLITE
Isaias is racing NNE at 30+ mph at this point, putting the heavy rain, thunderstorms, and wind in our backyard some time between 11am and 2pm as opposed to late afternoon/evening previously forecasted.
This works to our advantage in certain ways, including the subject of coastal flooding. While coastal flooding may still be an issue, Isaias will now be crossing over the area just before or during low tide. The high tide cycle at 8pm will still be an issue, but it should be on the lower end of that 1-3ft surge spectrum. That being said, those who live along the immediate shore with waterfront property, especially along the bays, still need to take action to protect personal property. Travelers also need to be weary this evening when avoiding roads that typically flood out during strong Nor’easters combined with a full moon.
Once the show gets started and that heavy band of rain and storms moves in, expect torrential rain, localized street flooding, and winds gusting to 60-70mph. Brief tornadoes are also possible, which is something I discussed in my live feed yesterday. After Isaias passes, we’ll have a stiff breeze for an hour or two on the back end before things begin to settle down.
REGIONAL RADAR
Everything is gone tomorrow, and we should enjoy a nice sunny day with very warm temps. Expect highs in the upper 80’s to possibly near 90.
LOCAL RADAR NEW YORK CITY
For Thursday and Friday, it looks as if some moisture tries to push back against the coast. This has nothing to do with todays events. Look for partly sunny skies, a little “cooler” than expected, and the slight chance of a few scattered showers or storms each day. Highs in the low to mid 80’s.
LOCAL RADAR PHILADELPHIA
Some of that moisture may stick around Saturday, but we’ll have a pleasant day on Sunday under sunny skies. Highs both days in the mid 80’s.
