flows in and near recent wildfire burn scars.
* ADDITIONAL DETAILS...
- National Weather Service Meteorologists are forecasting heavy
rainfall over burn scars on the west slopes of the Cascades

* WHAT...Flash flooding and debris flows caused by excessive
rainfall continue to be possible. The greatest concern remains
over the 2024 burn areas associated with active wildfires, but
there is also a small probability that rainfall rates could
approach threshold values over burn areas from previous years.

Cascades of Lane County, Cascades of Marion and Linn Counties and
North Oregon Cascades and southwest Washington, including the
following area, South Washington Cascades.
* WHEN...From 2 PM PDT this afternoon through late tonight.
* IMPACTS...Heavy rainfall over Cascade burn areas during the period
of the watch. Residents near the 2024 burn areas associated with
active wildfires should prepare for potential flooding impacts. Be
sure to stay up to date with information from local authorities.
Heavy rainfall could trigger flash flooding of low-lying areas,
urbanized street flooding, and debris flows in and near recent
wildfire burn scars.
* ADDITIONAL DETAILS...
- National Weather Service Meteorologists are forecasting heavy
rainfall, which may lead to flash flooding and debris flows
over recent burn areas in the Cascades. Hourly rainfall rates
up to 0.75 inches per hour will be possible.

...STRONG TO SEVERE THUNDERSTORMS WILL IMPACT THE CASCADE
MOUNTAINS TODAY, EXTENDING TO THE EASTERN SLOPES, WHILE
SOUTHEASTERN OREGON SEES DRY, WINDY, AND UNSTABLE CONDITIONS...
.A potent weather system will bring a myriad of impacts to the
forecast area today. For the Cascade Mountains and east slopes,
strong to severe thunderstorms will trek across primarily the
spine of the Cascades starting in the afternoon down around
central Oregon, advancing northward into the Washington Cascades
by the evening. While storms along the Cascades are expected to be
accompanied by a significant wetting rain, isolated to scattered
storms extending into the east slopes and portions of the Columbia
Basin will be much drier, leading to critical fire weather
conditions due to abundant lightning with a lack of wetting rain.
For southeastern Oregon, this same weather system will usher in
hot and dry desert air, leading to breezy winds combined with low
RHs and locally unstable conditions. Showers and storms are not
anticipated to track as far east as southeastern Oregon.
Users should note that OR641 and WA691 are under partial Red Flag
Warnings. The Warned zones include only the western half of each
zone, and not the entirety of the zone.
The National Weather Service in Pendleton has issued a Red Flag
Warning for abundant lightning, which is in effect from 8 PM this
evening to 5 AM PDT Sunday. The Fire Weather Watch is no longer
in effect.
* AFFECTED AREA...Fire Weather Zone 690 Kittitas Valley.
* IMPACTS...Thunderstorms will be capable of producing frequent
cloud-to-ground lightning and erratic, gusty outflow winds.
This combination will promote conditions conducive to new fire
starts and rapid fire spread for new and existing fires.
* THUNDERSTORMS...Abundant lightning with frequent cloud-to-
ground lightning strikes.
* OUTFLOW WINDS...Gusty winds up to 50 mph.
