Heat Continues Inland, Cooler at the Coast
Tuesday will bring an overall cool down to the Central Coast, as the strong ridge of high pressure that brought all-time record heat to parts of California continues to move to the east. But, still expect excessive heat for inland areas over the next few days as the influence of the strong high nearby will keep highs 5-10ºF above normal. The ridge moving eastward will also allow for a slightly deeper onshore flow along the coast. A "rinse and repeat" cycle for coastal cities through mid-week with morning and late evening low clouds, and seasonable temps. Basically, it's our micro-climates at their finest with a wide range of temperatures between coast and inland cities. There is some relief from the heat coming. More details in the extended forecast.
AIR QUALITY: Good to Moderate
***EXCESSIVE HEAT WARNING***
… for the higher elevations (above 1000ft) of Monterey County and the mountains and higher elevation valleys (above 500ft) of San Benito County until 8PM Friday
*Dangerously hot conditions with temperatures up to 110.
*Most individuals will be at risk for heat-related illnesses without effective cooling or adequate hydration, especially with prolonged outdoor exposure. Without effective cooling and/or adequate hydration, heat-related illnesses including heat stroke will be a risk to everyone. Overnight lows will warm as well leading to poor relief from the heat specifically in elevated terrain and interior areas.
*An exceptionally dangerous situation continues to unfold over the next couple of days we continue to move through this deadly heat event for inland areas. Another couple days of temperatures well above normal will lead to compounding effects among people and infrastructure, with the possibility of numerous heat related fatalities.
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.
Tuesday: Low clouds on the coast and nearby valleys early. Then, clouds clear back to the coast with some lingering on the south side of the bay during the afternoon. Expect coastal highs in the low 60s to mid 70s—warmest on the north side of the bay—and upper 70s to around 108ºF inland. Breezy west-northwesterly onshore winds becoming windy up valleys late.
Overnight: Low clouds thicken at the coast into sunset, filling the bay and most valleys by morning. Areas of fog, dense in spots, and patchy, light drizzle possible near the coast. Far interior locations will remain mostly clear. Lows mostly in the 50s across the Central Coast, warmest in the higher terrain.
Wednesday: Morning fog & clouds on the coast then clearing to partly cloudy skies on the coast and full sunshine inland. Slightly warmer with coastal highs in the low 60s to mid 70s—warmest on the north side of the bay—and low 80s to around 111ºF inland. Windy up valleys in the afternoon and early evening.
**HEAT ADVISORY**
…for the Santa Cruz Mountains, South Santa Clara County, and the lower elevation valleys of Monterey (<1000ft) and San Benito (<500ft) counties in effect from 11AM Wednesday until 8PM Friday.
*Temperatures up to 106 expected.
*Those sensitive to heat, such as the homeless, elderly, children, and pets will be at risk for heat-related illnesses. Those without effective cooling and/or adequate hydration will be at the greatest risk.
* ADDITIONAL DETAILS...Despite the downgrade from an Excessive Heat Warning to a Heat Advisory, the long duration of this heat wave will cause cumulative effects and this situation
remains dangerous.
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

Extended: Further expected by Thursday as winds shift and some monsoon moisture may also begin to stream in from the south. This will likely only be some high cloudcover, but we’ll have to watch for more. Cooling expected through the weekend, even for far interior locations.
