A summer heat wave sent temperatures soaring in the San Diego area Thursday, with sultry conditions expected to last through the weekend.
The hot spell pushed afternoon thermometer readings into the high 80s in many coastal areas, the high 90s to past 100 across inland communities, the high 80s to low 90s in the mountains and up to 116 in the deserts, according to the National Weather Service.
The swelter also set several heat records for the date. In Vista, the high was 91 degrees, exceeding the prior top mark of 90, set in 2009. In Chula Vista, the mercury hit 87, beating the old milestone of 84, set in 2005.
Several communities also saw their prior July 21 records tied, including Campo (105 degrees, previously set in 2006), Ramona (101, 1982) and Escondido (99, 1960).
An NWS heat advisory for the valleys, mountains and deserts will be in effect until 8 p.m. Sunday as persistent atmospheric high pressure lingers over Southern California, the federal agency advised.
San Diegans were advised to avoid potentially serious temperature- related ailments by staying well-hydrated, avoiding unnecessary outdoor labor, seeking out air-conditioned buildings and wearing lightweight, loose clothing.
