Fire danger?

When thunderstorms are in the forecast during the summer, there is an inherent risk of fire due to lightning strikes and the assumption of gusty winds. Right now the NW Mac preparedness level is 2.

Preparedness Level 2:
Situation: Relatively low risk, low complexity. Manageable activity utilizing established process,
protocols and relationships.
Workload: 2-4 active large fires and/or equivalent all risk incidents.
Available Capability: Geographic Area can effectively manage existing/anticipated activity AND still maintain surplus capability—OR—Low levels of activity observed/forecasted AND significant export of NW resources will limit Geographic Area capability to staff two or more IMTs.
