Long Island weather alerts

THIS EVENING AND OVERNIGHT

Our weather finally improves in Nassau and Suffolk counties following the powerful nor'easter that brought wind damage, coastal flooding, significant erosion and several inches of rain to parts of Long Island. It will stay mostly cloudy this evening, but any lingering drizzle is ending. Temperatures will be in the upper 50s to lower 60s this evening with a light breeze out of the northwest around 5 to 15 mph.
Overnight, clouds will clear a bit and it will become partly cloudy at times into early Tuesday morning, with low temperatures in the upper 50s and a north-northwest breeze around 5 to 15 mph.

COASTAL NOR'EASTER IMPACTS IMPROVING

  • Some brief minor coastal flooding in southern Nassau and southwestern Suffolk counties cannot be ruled out during the next few high tide cycles, but it will be much better than earlier high tides. A coastal flood statement is issued by the National Weather Service for this, which is the lowest level of coastal flooding alert.
  • Check local tides and shoreline alerts.

NOR'EASTER RECAP: PEAK GUSTS AND RAIN TOTALS

Beyond the coastal impacts of this past weekend's Nor'easter, the wind knocked down more than 1,200 trees across Long Island and 4 to nearly 7 inches of rain fell across much of the island, too. Thankfully, the storm is behind us, and nicer weather is on the way, but storm cleanup continues for many Long Islanders through the week.

There will be some partial clearing overnight with a light breeze. Wind: north-northwest 5 to 15 mph. Low temperatures will be in the 50s into early Tuesday morning.
TUESDAY: Partly sunny and a bit warmer with high temperatures around 70 degrees. Wind: Northwest to west 5 to 15 mph. Boaters: No advisories. Lows around 56 degrees.

SUNDAY: WEATHER TO WATCH - There is a chance for more weekend rain on Sunday. It would not be a multi-day major storm like this past weekend's Nor'easter, thankfully, but another inch or so of rain cannot be ruled out at this time.

Highs around 65 degrees. Lows near 58 degrees.
