The dense fog that's enveloped the region, especially along the Greenwich coastline has limited visibility to a quarter-mile or less, creating hazardous driving conditions, according to the National Weather Service.
"If driving, slow down ... use your low-beam headlights and leave plenty of distance ahead of you in case a sudden stop is needed," the weather service said in a "Dense Fog Advisory" statement. For good measure, the weather service issued a "Hazardous Weather Outlook" because of the fog.
The mild air over the region this afternoon, combined with moisture from this morning's rain is being cooled by the deep snowpack to form the dense fog, according to the NWS.
The NWS forecast has the fog dissipating by 2 a.m. Monday.
Here's the weather service's latest Darien-specific forecast:
- Monday night: Widespread dense fog before 2 a.m. Otherwise, cloudy, then gradually becoming partly cloudy, with a low around 34. Light and variable wind becoming west 10 to 15 mph in the evening.
- Tuesday: Mostly sunny, with a high near 47. Breezy, with a west wind 15 to 21 mph.
- Tuesday night: Mostly clear, with a low around 26. West wind 13 to 16 mph.
