Nearly 100,000 San Diegans could loose power during the next round of power shutoffs after the National Weather Service issued another Red Flag Warning for the region for Monday and Tuesday as Santa Ana winds return.

This weekend's cool temperatures and higher humidity are expected to give way to more Santa Anas and a new red flag warning Monday.

Red flag criteria is generally when relative humidity is at 15% or less, combined with sustained winds and/or gusts of 25 mph or greater. Both of these conditions must occur simultaneously for at least 3 hours in a 12 hour period, according to the NWS.

A red flag warning due to wildfire danger will be in effect from 10 a.m. Monday to at least 10 p.m. Tuesday for inland valleys and mountain areas throughout the county, according to the National Weather Service.
