Dense fog takes over NYC, in photos

The story of the morning, undoubtedly, was the development of dense fog which initially began in only patchy areas of the suburbs early this morning. But by sunrise the fog had lowered and thickened, in addition to spreading throughout the area — including into lower manhattan. The sunrise and aforementioned development of dense, low fog created a terrific (and somewhat rare) picture opportunity as the tops of building and bridges stuck out of the low cloud deck.

Often misunderstood, fog forms as water vapor condenses into tiny water droplets in the lower levels of the atmosphere. Fog is not water vapor itself (Water vapor cannot be seen), nor is it “smog”, a variation of the word which is used to describe lowered visibilities that occur as a result of pollution. But this morning was a more classic case of low fog, more typical in London or San Francisco. The occurrence was a terrific photo opportunity for some of New York City’s best photographers (and webcams). We’ve included some of the best shots below.

The National Weather Service continues a Dense Fog Advisory through noon today, and also urges caution for those who are traveling. Visibilities near zero are possible in some areas, and the fog is expected to cause delays not only on the roads but also at the area airports. The fog is expected to lift by this afternoon, with a chance of scattered showers and high temperatures generally in the mid to upper 40’s.
