...Synopsis...
Elevated fire weather conditions are expected to persist along the
southern CA coast through at least the morning hours today. A
prolonged offshore wind event continues to wane along the southern
CA coast, but 06 UTC surface observations continue to show areas of
elevated to critical fire weather conditions within the higher
coastal terrain. Multiple sites continue to report sustained
offshore winds of 15-20 mph with frequent gusts of 25-35 mph.
Additionally, nearly 12 hours of downslope warming/drying has
resulted in widespread RH reductions into the single digits and
teens. These conditions are expected to persist through the morning
hours as a surface high over the Great Basin migrates east in the
wake of a highly amplified upper trough over the central U.S.
Upper-level ridging building through the day will promote
diminishing low- to mid-level winds by afternoon, but ample diurnal
heating and some degree of subsidence warming will maintain the very
dry conditions. As such, the primary fire weather concern will be
focused during the morning hours with dry, but calmer, conditions
through the afternoon.
