A wind advisory is scheduled to go into effect across the Bay Area at 11\u00a0p.m. on Sunday as forecasters watch for gusts up to 60 mph in higher elevations spanning from the East Bay hills to the North Bay mountains, sparking fire weather concerns while temperatures heat up.\u00a0<\/p>\n
Rick Canepa, a meteorologist for the National Weather Service\u2019s Bay Area office, said most people likely won\u2019t see wind speeds higher than 15 to 30 mph. \u201cBut it\u2019s going to blow around unsecured objects and may cause a few power outages<\/a>,\u201d he said Sunday morning. (PG&E declared its first major Public Safety Power Shutoffs of the fire season on Sunday, with conditions prompting the closure of Rockville Hills Regional Park in Fairfield.) \u201cIt can also cause some driving difficulties and dry out some of the finer fuels.\u201d<\/p>\n The culprit is a low-pressure system forming in the Great Basin, which is leaving an area of high pressure in its wake that\u2019s expected to build Sunday night into Monday morning over Northern California. \u201cWhat we see as a result of this are down-sloping winds<\/a>, which force air to slope downward from the mountains,\u201d Canepa explained. \u201cThat tends to compress warm air and dry it out, so high temperatures will steadily climb this week with each passing day.\u201d<\/p>\n
