Normally sweet smelling residents of  communities from La Jolla, Solana Beach and Encinitas to Mira Mesa and Rancho Bernardo are reporting something stinks and they don't know what it is.

Authorities are investigating reports from around San Diego County of a strong odor some say resembles jet fuel, or grungy aftershave. People around Rancho Santa Fe and Del Dios compared the strange smell to kind of ammonia/bleach, very vanilla tasting. Yeech.

The stinking calls started around 2 p.m. People at Encinitas, Solana Beach, Pacific Beach, Mira Mesa and La Jolla reported the odd odor.

A public affairs spokesman at MCAS Miramar said the odor can be smelled at the base, but noted that base air operations have had not reported any fuel spills or aircraft that had to dump jet fuel in the county area.

An FAA spokesman said the agency was not aware of any fuel dumping being carried out on Wednesday.

Mario Aguilar of the Scripps Institution of Oceanography said he did not know of any algae blooms or anything organic that could be causing the smell.

Residents living in inland areas such as North Park, Hillcrest and Rancho Bernardo have said they can smell the odor in their area.

The San Diego Fire-Rescue Department has confirmed they have received numerous calls regarding the smell.

SDG&E officials confirmed they have technicians in the community trying to determine the source of the smell.
