Tips to Stay Safe
A Heat Advisory means dangerous heat conditions are happening now or soon. Take action before, during and after the heat to stay safe.
- Stay in air-conditioned spaces if possible. Find cooling centers or places with AC in your community that you can go to, like libraries or shopping malls.
- Stay hydrated and stock up on clean drinking water to get you through multiple days of heat.
- Reschedule outdoor activities for cooler times of the day, and take breaks in the shade or air conditioning.
- Cover windows with curtains or shades, or use window reflectors designed to reflect heat back outside.
- Check on friends, family, and neighbors, especially those who do not have air conditioning or spend much of their time alone.
Make sure you know the signs of heat-related illness and how to respond.

Issued by NWS Seattle WA
The National Weather Service in Seattle has issued a Fire Weather Watch for lightning and gusty outflow winds, which is in effect from Wednesday afternoon through Thursday afternoon.
Affected Area
Fire Weather Zone 655 Black Hills and Southwest Interior Lowlands and Fire Weather Zone 659 West Slopes of the Central Cascades Generally above 1500 Feet.
Lightning
Isolated to scattered thunderstorm coverage is possible across the southern Cascade Mountains and portions of southwest Washington. Thunderstorms will develop late Wednesday night and move from south to north across the area.
Outflow Winds
Any storms that develop will be capable of gusty and erratic outflow winds between 25 and 30 miles per hour. Outflow winds can occur ahead of and behind storms and cause erratic wind directions.
Impacts
Scattered lightning in dry fuels can cause multiple fire starts. Thunderstorms can also bring sudden sharp wind shifts on existing fires, causing rapid changes in a fire's rate of spread and direction of spread. Thunderstorm outflow winds can be a threat for several hours following the start of a new lightning-caused fire. If a fire were to begin, air quality may diminish in the surrounding area.
What to Do
A Fire Weather Watch means that there is a potential for critical fire weather conditions to develop. Monitor the forecasts for possible Red Flag Warnings.
Areas Impacted
- Black Hills and Southwest Interior Lowlands
- West Slopes of the Central Cascades Generally above 1500 Feet
