Oct 13, 8:52 PM Oct 14, 3:00 PM
WHAT: Flash flooding and debris flows caused by excessive
rainfall are possible.

WHERE: This Flood Watch is specifically for areas in and nearby
the recent burn scars of San Luis Obispo, Santa Barbara, Ventura,
and Los Angeles Counties. These burns scars are the Gifford,
Madre, Lake, Apache, Mountain, Post, King, Canyon, Hughes, Hurst,
Kenneth, Franklin, Palisades, Sunset, Lidia, Hawk, Eaton, and
Bridge burn scars.

WHEN: Through Tuesday afternoon.

IMPACTS: Potential for brief heavy rainfall over the burn scars
may trigger hazardous and damaging flooding and debris flows.
Flooding may also occur in poor drainage and urban areas.
Low-water crossings may be flooded.

ADDITIONAL DETAILS:
- Peak rates of 0.25 to 0.50 inch per hour with rates locally
to 0.80 inch hour are possible. There is a 10 percent chance
of rates to 1.0 inch per hour (due to thunderstorms or heavy
showers). Additionally, the thunderstorm threat will bring
concern for higher intensity sub-hourly rainfall rates that
may reach burn scar debris flow thresholds.
