Dense Fog Advisory In Effect Overnight Through Morning Rush Hour

HUDSON VALLEY, NY — The National Weather Service is warning of dangerous patchy fog in the Hudson Valley that could reduce visibility to less than a quarter mile.

The NWS issued a special weather statement warning of dangerous fog conditions in Westchester, Rockland, Orange, Dutchess and Putnam counties. Parts of New York City, Long Island and New England will also see patchy dense fog lowering visibilities to a quarter of a mile or less in some locations.

The fog is expected to last through the night and dense fog may become more widespread over the next several hours.

Areas on and near the water are faring even worse. The weather service has issued a dense fog advisory for much of the Long Island Sound and the Northeast coastline from New York City to Boston.

Inexperienced mariners, especially those operating smaller vessels, should avoid navigating in these hazardous conditions, according to the NOAA. If boaters must navigate, proceed with caution. Use proper fog signals. Make sure all running lights are on. Remember to use radar and a compass.

Inland, the NWS is urging motorists to exercise caution and be prepared for rapidly changing visibilities. Slow down and allow extra distance between vehicles. Also, use low beams in the fog.

Conditions are expected to improve after sunrise at 7:05 a.m. with the last of the fog advisories scheduled to expire by 11 a.m. Friday.
