A dense fog and heavy rain are creating hazardous driving conditions across the Boston area, with visibility reduced to just 2 miles on I-93 and the Mass Pike. The National Weather Service has issued a weather alert, warning of continued rain, gusty winds, and patchy fog that will linger through late morning, leading to slower travel and potential delays at Logan Airport.

Why it matters

Severe weather events like this can significantly impact commutes, flights, and daily routines for residents and businesses in the Boston metro area. Reduced visibility and slick roads pose safety risks and can lead to traffic jams, delays, and accidents if drivers do not adjust their behavior accordingly.

The details

According to the National Weather Service, the Boston region is experiencing a combination of dense fog and heavy rain that has dropped visibility to around 2 miles at Logan Airport. Winds may gust up to 29 mph, pushing bands of rain across eastern Massachusetts and causing visibility to fluctuate. Drivers can expect slower travel on major highways like I-93 and the Mass Pike, with bridges and tunnels remaining slick throughout the morning. Minor flight delays at Logan Airport are also possible due to the low cloud cover.

  • The weather alert is in effect through late morning on April 19, 2026.
