San Diego's coastline was socked in by dense fog Friday morning, creating conditions of low visibility that may affect commuters, weathercasters said.
The National Weather Service issued a dense fog advisory until 8 a.m. Friday due to a thick patch of fog extending inland from the coast to Interstate 5.
The more inland I-15 was experiencing some fog on the roadways as well, though not as severe.
Visibility in some parts of the region, including La Jolla, Downtown San Diego and Mira Mesa, was reduced to less than a quarter-mile, NBC 7 Meteorologist Sheena Parveen said.
Other areas strongly affected by fog include Chula Vista, City Heights, La Mesa, El Cajon and Escondido, according to Parveen.
Flight delays may also be possible at San Diego International Airport, NWS said. Check for delays here.
Fog is expected to clear by 8 a.m.
