.DISCUSSION...
Generally moderate southeasterly winds will prevail, at around
12-14 mph with stronger sea breezes at times. RH values may
briefly drop to the low to mid 50s along the west and southern
plains but will quickly rebound with the sea breeze and diurnally
induced afternoon showers. Given these expected conditions, the
fire danger risk is anticipated to remain low today.
