Heat Alert
A ridge of high pressure will really dominate our weather for most of this week. The hot dome of air will be centered over California sending temperatures up well above normal for several days. At the coast, flow will generally remain onshore, but the cool breezes won’t make it all that far inland. A cut off area of low pressure will eventually approach the coast from the southwest which will ultimately cool us down. It will also bring clouds and perhaps a chance for rain or thunderstorms by next weekend.
Overnight: Mostly clear with a few low clouds/fog possible around the bay. Expect coastal lows in the upper 40s to low 50s with 40s for inland valleys and 50s in the hills.
*Heat Advisory*
… for San Benito and Santa Clara Counties, along with inland Monterey & Santa Cruz Counties from 11AM Monday until 7PM Thursday.
The excessive heat watch has been cancelled for coastal areas. However, temperatures in these locations will warm to 10 to 15 degrees above seasonal averages from Monday through potentially Thursday.
Those most vulnerable to the heat should still take necessary precautions through this prolonged period of heat.
Expect an extended period of hot daytime temperatures with limited overnight relief. Near record to record temperatures are possible during the peak of the heat event. Daytime temperatures likely to peak on Tuesday and/or Wednesday.
Heat related illnesses such as heat exhaustion and heat stroke can occur due to prolonged exposure to hot temperatures, including the general population. People most vulnerable include those who are spending lots of time outdoors, those without air conditioning, young children, the elderly and those with chronic ailments. Additional societal impacts due to the movement of people seeking relief from the heat from hotter areas inland.
Widespread 90s to low 100s daytime temperatures are expected for inland areas on the hottest days of Tuesday and Wednesday. The Santa Cruz coast could rise to the upper 80s to low 90s during these hottest days. Other coastal areas should remain relatively cooler than surrounding inland areas given light onshore flow (70s to around 80). Significant temperature differences from the coast to a few miles inland could drive an excessive number of persons towards the coast to seek relief from the heat. Individuals are advised to check with local authorities on potential closures of parks and beaches and be aware of any special requirements for visiting such areas. Overnight lows will range from the upper 50s to low 60s which may limit the impact of typical overnight relief in the
Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Young children, disabled or elderly adults, 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: Expect mostly sunny skies for most of next week with hot daytime temperatures and warm nights. Immediate coastal areas will have cooling sea breezes, but they won’t reach very far inland. Clouds will be on the increase late in the week with a chance of showers/thunderstorms by Saturday.
