...Abundant Lightning On Dry Fuels Expected Wednesday...

.Instability increases Wednesday with scattered thunderstorms
possible. Thunderstorms are expected to start dry, and become
wetter in time. In addition to the threat of new fire starts, a
dry and unstable layer will support gusty and erratic outflow
winds with any thunderstorms. Plume-dominated fire activity will
be possible with new or existing fires due to hot, dry and
unstable conditions.

PDT THIS EVENING FOR ABUNDANT LIGHTNING ON DRY FUELS FOR FIRE
WEATHER ZONES 280, 281, 284, 285, 617, 620, 621, 622, 623, 624,
AND 625...

* Impacts: Lightning and high fire danger will likely result in
new fire starts. Gusty thunderstorm winds could contribute to
fire spread. Despite rainfall, initial attack resources could
be overwhelmed and holdover fires are possible.

281...284 and 285, including the McKinney and Yeti Fires,
Seiad Valley, Macdoel, Tennant, Canby, Alturas, and portions

near thunderstorms.
