A strong nor’easter parked off the East Coast is set to deliver increased wind and more widespread rainfall across central and eastern Pennsylvania on Sunday, the National Weather Service and local forecasts said.
Storm track and timing
Rain and gusty winds already affected parts of the region Saturday as the system moved into position. A lull is expected overnight before precipitation and stronger gusts pick up again near sunrise Sunday, with the heaviest periods of rain and the strongest winds tracking closer to the New Jersey coast.
The Weather Channel’s local forecast for the Harrisburg area shows the heaviest rain arriving between about 8 a.m. and 5 p.m. Sunday. Meteorologists say the bulk of the nor’easter’s moisture and wind should exit the Commonwealth by Monday morning, although some lingering showers are possible across eastern Pennsylvania afterward.
Winds, rain totals and local impacts
So far, most wind gusts across central and eastern Pennsylvania have remained below 30 mph. One exception: Lancaster Airport recorded a gust of 33 mph Saturday morning.
As the storm shifts eastward toward New Jersey, forecasters expect widespread gusts of 25–30 mph across central Pennsylvania and stronger gusts — generally 35–40 mph — in areas of more complex terrain in eastern counties.
Because many trees still retain leaves this time of year, forecasters warned that isolated power outages and minor tree damage are possible where the stronger gusts occur. The weather service said no widespread flooding is expected, although localized runoff and nuisance flooding have been reported along the Jersey Shore and in coastal Mid-Atlantic communities.
Where the heaviest rain is expected
Rain will become more widespread Sunday. Storm-total rainfall is expected to approach one inch in portions of Lancaster and Sullivan counties, according to the National Weather Service. Western Pennsylvania has remained largely dry, as dry air pushing in from the west has kept precipitation from advancing that far across the state.
- Central Pennsylvania: Widespread rain and gusts of 25–30 mph expected Sunday.
- Eastern Pennsylvania (complex terrain): Gusts of 35–40 mph possible; localized tree damage and outages possible.
- Western Pennsylvania: Mostly dry as of Saturday night due to dry air from the west.
| Area | Expected Gusts | Rainfall |
|---|---|---|
| Central Pennsylvania | 25–30 mph | Widespread showers |
| Eastern PA (complex terrain) | 35–40 mph | Periods of moderate rain |
| Lancaster & Sullivan counties | Variable | ~1 inch (storm total) |
| Lancaster Airport (observed) | 33 mph gust | — |
| Harrisburg region (timing) | — | About 8 a.m.–5 p.m. Sunday |
Practical advice for residents
State and local officials advise residents to prepare for gusty conditions and periods of rain through Sunday. Practical steps include securing loose outdoor items, driving cautiously on wet roads, and being ready for short-term power interruptions.
Motorists should be aware of reduced visibility in heavier downpours and the potential for debris on roadways where fallen limbs occur. Those traveling in or near higher terrain in eastern counties should expect the strongest gusts.
While the National Weather Service does not expect large-scale flooding across Pennsylvania from this particular storm, residents living in low-lying areas, along streams or where drainage is poor should monitor local conditions and alerts from emergency management offices.
The nor’easter’s effects on flights and coastal communities continue to be reported along the Jersey Shore and other Mid-Atlantic areas, where flooding and outages have been more pronounced.
Forecasters said the system will weaken as it moves offshore Monday, though clouds and occasional showers may linger across eastern counties into the start of the week.
For the latest conditions and any advisories, consult the National Weather Service forecast office serving your county and check local emergency-management pages for updates on power outages and road conditions.
