Tropical Storm Fay Is Vermont's Friend

Vermont is rarely hit by any kind of tropical system.

But when the Green Mountain State is hit by a tropical storm or depression or hurricane, it's pretty much always had news.

In the topsy-turvy year of 2020, though, Tropical Storm Fay, on balance, looks like it will help Vermont much more than it will hurt.

Since Fay is a tropical storm, which are always very wet and windy, the storm will be bad news for some people, though.

WHERE IT'S AT AND GOING

As of 8 a.m this morning, Tropical Storm Fay had top winds of 50 mph, mostly east of its center.It was about 100 miles or so south of the southern tip of New Jersey.

Tropical Storm Fay was northbound as of early this morning, and will continue in that direction as it picks up forward speed. It'll scrape past New Jersey, possibly even making landfall there.  If not, it will come ashore not far from New York City tonight

At this point, forecasts take Tropical Storm Fay up the Hudson River Valley into either eastern New York or western Vermont.  The official 5 a.m. Friday National Hurricane Center forecast track had Fay pretty much sitting right over my house in St. Albans, Vermont at around 2 p.m. Saturday. It will then head into Quebec.

I'm delighted this could happen. So are my gardens.  We welcome the prospect of a potential soaking.

Of course, by the time, Fay hits Vermont or nearby, it will have been downgraded to a tropical depression and it will be starting to transition to a non-tropical system.

If Fay is still at tropical storm strength by the time it hits Vermont, it will only be the fourth tropical storm known to have its center pass over somewhere in the Green Mountain State.

Two of those past tropical systems were devastating and deadly. Tropical Storm Irene killed at least six Vermonters and pretty much tied with 1927 as creating the worst flood in the state's history.

The Great New England Hurricane of 1938 also passed through Vermont, causing serious flooding and leveling tracts of forests with its winds. The 1938 storm decimated the maple sugar industry for years afterward.

FAY IS NOT MEAN LIKE THE OTHERS

Fay's effects will be far, far, less serious in Vermont than Irene or the 1938 storm.

Here's why:

1. It's weak, so doesn't have the power to unleash widespread torrential rains or damaging winds.  Wind gusts for almost all of us should stay below 35 mph. A few favored areas, perhaps including some of the western slopes of the Green Mountains, could see gusts as high as 45 mph.

2. It's fast. Fay will be rocketing northward and will only affect directly affect Vermont for several hours.  It might rain torrentially at times, but the rain won't last long enough to cause serious flooding. Some favored spots might get extra rain, causing local stream flooding, road washouts and urban flooding, but this is certainly no Irene.

3. Vermont is dry. Parts of the state are in a drought. That's why I'm liking Fay so much.  It could put a good dent in the dry conditions we have been having.

The thing I worry about most from Fay is not too much rain, but too little. Forecast tracks for Fay keep pushing it further west.  The heaviest rain with northbound tropical storms in the Northeast is to the west of their track.

If Fay goes up through New York State instead of through Vermont, we could miss out on the heaviest rain.   Right now, forecasts call for one to two inches of rain from Fay in Vermont, with locally higher amounts.

More rain and thunderstorms Sunday through Tuesday could offer additional help with the dry conditions.

Fay will also help break the heat somewhat.  We have one more hot day today, but the clouds and precipitation with Fay, and another disturbance approaching from the west, will encourage clouds, which will hold daytime temperatures down a little. It will still be miserably humid though, at least into Monday.

Some clouds from Fay will move northward across Vermont this afternoon, and those might actually temper the heat a little in southern  Vermont  It will still be blazing up north, though.

FAY'S EFFECTS ELSEWHERE

It isn't all fun and games with Tropical Storm Fay.  Closer to its landfall, Fay could easily dump enough rain to cause flooding. Flash flood watches are up for New Jersey, western Massachusetts, Connecticut, Delaware, far eastern Pennslyvania  and the Hudson River Valley and surrounding areas from Saratoga Springs south to New York City.

Some of the downpours with Fay are pretty intense.  Ocean City, Maryland had about 1.5 inches of rain in one hour, and 2.75 inches within just two hours, for instance.

Winds along some coastal areas could gust to 55 mph. Coastal flooding is likely to be minor.

Tropical storms like Fay can spin up tornadoes, so some are possible later today and tonight in and near Long Island, New York parts of far southern New England, the  New York City metro area and coastal New Jersey.
