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...From this evening 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
