September 4, 2026

The overnight storms are the item here, and they are on their way out rather than on their way in. The Storm Prediction Center's outlook issued at 9 p.m. Eastern drew a marginal risk of severe thunderstorms, its lowest of five steps, across a broad area that included New York City. A marginal risk means isolated severe storms are possible, not that a widespread event is expected. That outlook runs through 8 a.m. Eastern this morning.

For Friday itself, the Storm Prediction Center's next outlook keeps the marginal risk area centered further west and south, reaching Philadelphia. New York and New Jersey sit near its northern edge. New Jersey has two active National Weather Service alerts this morning; New York State appears in the national alert count but not among the states carrying land based alerts.

The Weather Prediction Center carries a marginal risk of excessive rainfall over the Mid-Atlantic for Friday into Saturday. That is the lowest of four steps and describes localized street flooding rather than a widespread event.

The practical action is small. If a storm parks over your route, waiting fifteen minutes is usually the whole solution. Do not drive into water across a road, which is the National Weather Service's Turn Around, Don't Drown guidance.

Puerto Rico and the United States Virgin Islands have no active weather alerts this morning and no tropical systems anywhere near them.

No large uncontained wildfires are burning in the region. Nationally the wildfire preparedness level stands at 5, its highest step, with 84 large uncontained fires and 20,245 personnel assigned. The year to date total is 52,626 fires and 8,265,751 acres, which is 126 percent of the ten year average for fires and 163 percent for acres. Those figures come from the National Interagency Fire Center report dated September 2, so they are one to two days behind this morning.

No grid emergencies or water system disruptions are reported across New York, New Jersey, Puerto Rico, or the Virgin Islands this morning. Isolated outages are ordinary after an overnight thunderstorm and are usually restored within hours.

No public health advisories specific to the Mid-Atlantic were confirmed this run. The Centers for Disease Control and Prevention's Health Alert Network archive could not be read this run, so this brief makes no claim about national health advisories in either direction.

The Atlantic basin is empty and expected to stay that way for a week. The National Hurricane Center's outlook issued at 8 p.m. Eastern on September 3 reports no tropical cyclones and states that formation is not expected during the next seven days.

That matters more here than the overnight thunderstorms do. September is normally the busiest month of the Atlantic season, and for the Mid-Atlantic the risk window runs through October. A quiet week in early September is a reprieve in the middle of the season rather than the end of it.

Puerto Rico and the Virgin Islands carry the region's most direct hurricane exposure and the least margin for a late start. A week with nothing in the basin is the right week to confirm that your flood insurance is in force, since new policies generally carry a waiting period, and to photograph your home's interior for your own records.

For New York and New Jersey the more common September hazard is inland flooding from a storm's remains rather than wind at the coast. Knowing whether your address sits in a flood zone is a question with a definite answer, and the calm week is when to look it up.
