Sunday Transition Day

An area of low pressure nearby will keep the marine layer deep into early Sunday which will mean widespread low clouds across the region. The low moves off to the southeast late in the day as high pressure builds to the west. This will set up a north-northeasterly pressure gradient and begin to push the winds offshore. Initially, this may help cut down on coastal clouds slightly, but Sunday’s temperatures will only be a couple of degrees warmer than Saturday. The north side of the bay will have the biggest swing as low level northwesterly flow takes over briefly Sunday afternoon. But Monday, the northeasterly offshore winds will then rule, bringing warm (becoming hot) dry air all the way to the coast. We’ll then sit through three very warm, if not hot days both inland and on the coast before cooler weather returns.

AIR QUALITY: Good

Rest of Sunday: Becoming mostly sunny on the coast with a few low clouds on the south side of the bay and sunny inland. Slightly warmer, with coastal high sin the mid-60s to mid-70s—warmest on the north side of the bay—and mid-70s to upper 90s inland. Windy up valleys late in the day, then breezy northeasterly offshore winds in the hills late.

Monday: Sunny and hot with coastal highs in the mid-70s to mid-90s and mid-90s to around 104ºF inland.

**HEAT ADVISORY**
…in effect from 11AM Monday until 11PM Wednesday for…

… coastal areas of Monterey & Santa Cruz Counties where temperatures up to 93ºF are expected…

… and for inland areas of Monterey, Santa Cruz, San Benito, and Santa Clara Counties where temperatures up to 105ºF are expected.

*Hot temperatures may cause heat illnesses to occur.

Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Young children and pets should never be left unattended in vehicles under any circumstances.

Take extra precautions if you work or spend time outside. When possible, reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear lightweight and loose-fitting clothing when possible. To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air-conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location.

Heat stroke is an emergency! Call 9 1 1.

Extended: Temperatures peak some 20-30ºF above normal on Tuesday before cooling slightly on Wednesday. A bigger cool-down will arrive on Thursday with more seasonable weather approaching the weekend.
