Tropical Storm Isaias- 8/3/2020 Update

  By

As of this evening Tropical Storm Isaias is located off the coast of South Carolina and progressing north towards our region. There are already some thunderstorms developing over NJ and heading towards our region, but the main effects of Isaias will not impact our area until late tomorrow morning into tomorrow evening.

At the peak of the storm, Long Island and NYC can expect to see sustained winds of between 30-50MPH, with the potential of gusts over 60MPH. I should note as seen in the model images below, wind gusts just above the surface will be somewhere between 70-90MPH. It is possible, though unlikely that some of these gusts may mix down during a thunderstorm during the morning and afternoon. For Long Island and NYC, this will be a mostly wind event with minimal rain. However, it is possible that there will be localized flooding in some locations due to thunderstorms that develop. Additionally, if you live along the south shore of Long Island, you can expect minor to moderate coastal flooding. This is due to winds from the S/SE pushing water up against the beaches and inlets. 

Overall, this will be a low to moderate impact tropical system for our region.

Hurricane Isaias- 8/1/20 Morning Update

  By

As of this morning, Hurricane Isaias is moving northwestward through the Bahamas. Isaias’ satellite appearance is somewhat disorganized and it has remained level in-terms of strength. Throughout this morning and this afternoon little strengthening is expected as Isaias will continue to struggle with dry air and wind-shear. Isaias will approach the coast of Florida late tonight through early Monday morning and begin to weaken. From there it will turn North and head up along the coast. At this point in time, I am still not confident in a specific forecast, though it does look likely that we will at minimum see some rain connected with the remnants of Isaias. 

For now it looks like the impacts to our region will be minimal outside of the potential for moderate to heavy rains and minor winds. We should all keep a close eye on Isaias as the forecast with storms like this are always difficult to nail down in the long range. More to come later today as needed.
