It's not because it's only 94.
It's in effect for the week going into triple digit temps, as high fire danger and elderly/people without a/c need to adequately prepare for the week(s) ahead. Suddenly going from 70 to 105 in a few days, it can have serious effects for some people.
Trust me there is a HUGE difference between 105° and 117°. In another month we will see 100° at midnight so a high of 105° is spring for us.
