Dense Fog Hits NYC: Commuter Delays Expected April 6, 2026

A dense fog advisory is in effect for the New York metropolitan area until 9 a.m. Monday, with visibility reduced to less than a quarter-mile in some locations. The fog is expected to lift by late morning, giving way to mostly cloudy skies and a high near 62°F. Light rain will develop in the afternoon, potentially impacting the evening commute. In London, expect a damp start with light rain and temperatures around 48°F, though conditions should improve by afternoon. Tokyo will see partly cloudy skies and a high of 64°F. The inclement weather on the U.S. East Coast may cause minor delays at regional airports and slower traffic on highways during the morning rush hour.
