Heat Wave in USA on August 29 2017 02:38 AM (UTC).
Temperatures hit 100 degrees or more in nearly 20 communities across San Diego County on Saturday as the region suffered through the sixth - and possibly final day, of a grueling heat wave. The National Weather Service says that remnants of Tropical Storm Lidia changed circulation patterns in Southern California, causing hot, dry winds to flow from the deserts to the sea, much like Santa Ana winds. Those remnants are expected to produce strong winds in countywide on Sunday, and could produce rain from the mountains to the coast, especially during the afternoon and evening. "A heat wave isn't unusual this time of year, but we only get something that last this long like every two to three years," said Brett Albright, a forecaster at the National Weather Service.
