Residents across the San Francisco Bay Area are being urged to prepare for a string of scorching days ahead as the National Weather Service has issued an Excessive Heat Warning effective from Monday afternoon through Wednesday evening, primarily for the East Bay Hills, Interior Valleys, the Santa Lucia Mountains, including the Los Padres National Forest, and Interior Monterey County encompassing Pinnacles National Park. According to the National Weather Service, we can expect "Dangerously hot conditions with daytime temperatures reaching the upper 90s to lower 100s", that may even soar up to a sweltering 108 degrees inland.
The heat is not restricted to daytime alone, as nighttime temperatures in these areas are predicted to stay warm, lingering in the 60s and 70s. A Heat Advisory will also take effect simultaneously for other locales, including facets of the North Bay, South Bay, Santa Cruz Mountains, and the Southern Salinas Valley. During this period, these regions could closely see temperatures hitting the 90s to near 100 degrees.
Concurrently, a Coastal Flood Advisory adds to the region's weather woes, remaining in effect until the early hours of Tuesday for the bayside shorelines of San Francisco Bay and San Pablo Bay. The alert, as described by the National Weather Service, cites that "tidal levels are increasing as a result of higher astronomical tides", which could lead to minor flooding in certain low-lying areas during high tide situations.
The week's forecast isn't solely centered around heat and coastal concerns. According to their Area Forecast Discussion, the National Weather Service also signals a potential caveat for thunderstorms, particularly Tuesday evening into Wednesday. The interplay of monsoonal moisture and the movement of an upper low across the southern West Coast has created a chance for elevated convection, although, as of now, the "chance is very low, but non-zero."
For mariners, the conditions are rough, with a Gale Warning in place until Monday evening for most coastal waters due to persistently strong northwest winds. Seas are expected to reach heights of 10 to 13 feet, with the "elevated wave heights over the outer waters" likely to endure through midweek, according to NWS. Those on land are encouraged to stay hydrated, find air-conditioned environments, and check up on vulnerable populations, such as the elderly and those without access to heat-relief resources, during this period of intense weather.
