Active Weather
There are no active watches, warnings, or advisories anywhere in New York, New Jersey, Puerto Rico, or the U.S. Virgin Islands as of 1:17 AM Eastern time. What the region does have is a forecast worth reading before the afternoon.
The Storm Prediction Center, the National Weather Service office that forecasts severe thunderstorms and tornadoes for the whole country, issued an outlook covering Wednesday daytime that places a slight risk of severe thunderstorms from eastern Ohio into western New York. Slight risk is the second of five levels. It means scattered severe storms are expected somewhere in that area, not that any one town will get one.
The specific hazard is damaging wind. The center puts the probability of severe wind gusts within 25 miles of any point in western New York at 15 percent, and adds a 2 percent tornado probability that is centered further west over eastern Ohio and northwest Pennsylvania rather than New York. The forecaster's reasoning is that storms should organize into a line along a cold front, and a mostly linear storm mode limits the tornado threat even though the low level winds strengthen through the afternoon.
In practical terms, a 15 percent severe wind probability is the kind of afternoon where a line of storms comes through with gusts strong enough to take down limbs and cause scattered power outages. If you are in Buffalo, Rochester, Jamestown, or the Southern Tier, the useful steps are the small ones done before lunch: bring in or tie down patio furniture and trash bins, charge phones and any battery bank, and know where your flashlights are. New York City, Long Island, the Hudson Valley, and New Jersey sit outside the slight risk area.
One note on timing. This outlook was issued Tuesday afternoon as a day 2 product. The Storm Prediction Center refreshes its day 1 outlook through Wednesday morning, so the risk area may shift. The current version is always at spc.noaa.gov.
Puerto Rico and the U.S. Virgin Islands have no alerts. Puerto Rico remains in widespread severe to extreme drought, though the U.S. Drought Monitor recorded improvement in parts of the island after rainfall from the remnants of Tropical Storm Dolly.
Infrastructure
Nothing active. No outage events, water notices, or transportation disruptions are reported across the region.
There are no large wildfires in the region in the National Interagency Fire Center's September 8 situation report.
No open Federal Emergency Management Agency disaster declarations were issued for New York, New Jersey, Puerto Rico, or the U.S. Virgin Islands in August or September. The most recent declarations nationally were a five state group covering severe storms and flooding in the Plains and Midwest on September 1.
Public Health
No active air quality alerts in New York, New Jersey, Puerto Rico, or the U.S. Virgin Islands.
The Centers for Disease Control and Prevention Health Alert Network archive index could not be read again this morning, so we are not able to confirm either way whether a new national health advisory has posted. The most recent notice we could open directly was issued August 11 and is written for clinicians rather than households. If you want to check for yourself, the archive lives at emergency.cdc.gov/han.
Watch Item
The National Hurricane Center's Atlantic tropical weather outlook, issued at 2 AM Eastern time this morning, says tropical cyclone formation is not expected during the next seven days. This is the climatological peak of the Atlantic season, so an empty basin is worth noticing rather than assuming.
For this coastline that is the number that matters most in early September. New York and New Jersey see their tropical risk from systems that form in the deep Atlantic and turn north, and seven days of no formation means nothing can reach here from the tropics before the middle of next week at the earliest. That is a working window rather than an all clear for the season.
The Weather Prediction Center's day 2 excessive rainfall outlook, valid through Thursday morning, includes New York in a marginal risk band that also covers Pennsylvania, Vermont, and New Hampshire. Marginal is the lowest of four levels. The center considered raising the Ohio Valley portion of this band to slight risk and decided against it, writing that the quick forward speed of the storms was the deciding factor and that a later model run might change that if storm motion slows. That is the thing to watch through Wednesday: slower storms over the same ground is what turns an ordinary rain into a flooding rain.
If storms do produce street flooding Wednesday evening, the single rule that matters is the National Weather Service's Turn Around, Don't Drown guidance. Do not drive into water across a road. You cannot see whether the roadbed underneath is still there.
