Watches & Warnings

Flash Flood Watch
Issued: 9:10 AM PDT Aug. 22, 2017 – National Weather Service

... Flash Flood Watch in effect from 2 PM PDT this afternoon
through this evening...

The National Weather Service in Medford has issued a:

* Flash Flood Watch for portions of northern California and south
central Oregon, including the following areas, in northern
California, wildfire burn scars in south central Siskiyou County
to include the wallow, Fay, garden, and grizzly fires. In
southwestern Oregon and northwestern Siskiyou County to include
the Miller complex of fires, and in Modoc County to include the
Modoc July complex and Parker 2 fire.

* From 2 PM PDT this afternoon through this evening

* isolated to scattered thunderstorms are expected. Some of these
storms will be slow-moving and have heavy rain with them, and
there is potential for flash flooding over recent wildfire burn
scars. There is some uncertainty in terms of storm coverage due
to heavy smoke limiting surface heating. Specifically, heavy
smoke may prevent storms from forming in extreme western
Siskiyou County.

* Despite heavy rain occurring with some storms, lightning is
expected outside of the storm cores, and abundant lightning on
dry fuels will cause new fire starts.

Precautionary/preparedness actions...

A Flash Flood Watch means that conditions may develop that lead
to flash flooding. Flash flooding is a very dangerous situation.

You should monitor later forecasts and be prepared to take action
should flash flood warnings be issued.

Landslides and debris flows are possible during this flood event.
People, structures and roads located below steep slopes, in
canyons and near the mouths of canyons may be at serious risk
from rapidly moving landslides.

Fire Weather Warning, Fire Weather Watch
Issued: 3:24 AM PDT Aug. 22, 2017 – National Weather Service

... Red flag warning remains in effect from 2 PM to 11 PM PDT
Tuesday for abundant lightning on dry fuels for fire weather zones
281 and 285... and portions of fire weather zones 280, 284, 623,
624, and 625...

... Fire Weather Watch remains in effect from Wednesday afternoon
through Wednesday evening for abundant lightning on dry fuels for
portions of fire weather zones 280... 281... 284... 285... 623... 624
and 625...


* impacts: abundant lightning and high to very high fire danger
will result in new fire starts. Gusty outflow winds could
also contribute to fire spread. While some of the
thunderstorms could bring wetting rainfall, initial attack
resources could become overwhelmed by the number of new fire
starts, and holdover fires are likely.

* Affected area by the red flag warning:
- in northern CA fire zones... 280 east of Seiad Valley... 281... most
of 284... 285.
- In southern or fire zones... 623 south of Mount McLoughlin... most
of 624... western 625.

* Thunderstorms: thunderstorms will begin first over northern
California this afternoon and then are expected to develop over
the mountains of the east side. Storms are then likely to spread
and develop northward into the southern Oregon Cascades and
Siskiyous this evening. Isolated thunderstorms are likely to
continue into tonight.

* Outflow winds: gusty and erratic winds of 30 to 40 mph are
possible from stronger thunderstorms.

* View the hazard area in detail at:
http://www.Wrh.NOAA.Gov/map/?Wfo=mfr

* watch details: the thunderstorm threat will shift northeastward
on Wednesday, but will still include portions of the mentioned
fire weather zones.

Precautionary/preparedness actions...

A red flag warning means that critical fire weather conditions
are either occurring now, or will shortly. Scattered
thunderstorms combined with dry fuels create conditions where
many fire starts may occur in a short period of time.

A Fire Weather Watch means that critical fire weather conditions
are forecast to occur. Listen for later forecasts and possible
red flag warnings.
