  1. @ai6yr I want one too! We live in the wildland urban interface (WUI) in King County which adjoins the south side of Snohomish County.

    Just did a quick search and wound up chatting with a state staffer. Surprise!!! Turns out the King County Wildfire Protection Plan was approved earlier today.

    Might take a day or more but when I get a link I will certainly share it.

  2. "Smoky Skies in the Pacific Northwest" by #NASA Earth Observatory - Sept 13 satellite imagery shows fires and smoke across Washington, Idaho, Montana and British Columbia. Besides unhealthy particulates in smoky air, study has shown effects of fires include effects on water quality and less-restrained runoff in burned areas. earthobservatory.nasa.gov/imag #WAfire #WAwx #IDfire #IDwx #MTfire #MTwx #BCfire #BCwx #weather #PNW

  3. The peak of the ongoing heat wave impacting the Pacific Northwest will draw to a close Wednesday evening. For the Tri-Cities, Yakima, and surrounding areas, temperatures will moderate from around 105° to 110°F (40° to 43°C) to “only” around 100°F (38°C). First, though, the region will go through breezy conditions Wednesday evening.

    Wind speeds won’t match the standard fall and winter wind storms Eastern Washington and Eastern Oregon can receive, but gusts to 25 mph (40 km/h) are possible around the Tri-Cities and Yakima. In the Columbia Gorge and Kittitas Valley, gusts to 40 mph (65 km/h) are possible.

    The strongest gusts will be outside of towns where trees and buildings don’t slow things down. Locations west of Hermiston will get the strongest gap flow winds coming through the Columbia Gorge.

    This wind will be generated by high surface pressure moving in west of the Cascades while the thermal trough (low pressure caused by heat) shifts from the Columbia Basin toward Idaho and Utah. The Cascades form a barrier to incoming high pressure, with wind surging through gaps in the mountains like the Columbia Gorge and Snoqualmie Pass.

    Forecast details

    The forecast has prompted the National Weather Service in Pendleton to issue a fire weather watch from 14:00 to 23:00 Wednesday for the Columbia Basin and Yakima Valley. A red flag warning is also in effect for the Blue, Strawberry, and Wallowa Mountains from 12:00 Tuesday to 23:00 Wednesday.

    Wind will accompany very low relative humidity and very hot temperatures since the Columbia Basin will be insulated from the cooler marine air that will be filtering into the I-5 Corridor. During the afternoon and evening hours, relative humidity may get as low as 10% in the Columbia Basin and 7% in the mountains.

    Peak temperatures on Wednesday will likely be around 105° to 108°F (40° to 42°C) in low elevation locations before slowly moderating into the overnight hours. Cooler temperatures are expected in the mountains, but not cool enough to remove the significant fire danger.

    Gusty winds, low relative humidity, and high temperatures combine to make it easy for wildfires to spread rapidly. Any fires that develop in both the desert areas and mountain forests could make long-distance runs before temperatures cool enough to suppress fire behavior after midnight.

    Preparation

    Not everyone will be threatened by a fire on Wednesday but now is a good time to prepare in case one does pop up near you. Have a go bag near your front door with critical documents and medication as well as water, some food, entertainment, cash, and portable chargers to supply everyone in your household.

    Have a plan now for where you will go in case you need to evacuate. This can be any safe place you feel comfortable going that is more than a few miles from your house. Consider close relatives and friends. Make sure your yard is clear of flammable debris.

    Preparation before an emergency saves lives.

    Extended forecast

    The center of the heatwave shifts eastward during the second half of the week but temperatures are forecast to remain above average in and around the Columbia Basin. Highs around 100°F (38°C) are forecast for the Tri-Cities Thursday through Monday.

    If the Tri-Cities Airport can hit 100°F (38°C) on Thursday, the area has a chance of getting close to or breaking the record streak for 100° days. Thursday looks like the coolest day of the week with a forecast high between 98° and 101°F (37° and 39°C). The average high for this time of year is 92°F (33°C).

    A dying dry cold front associated with low pressure in Alaska may cross the Pacific Northwest early next week to create another round of fire weather concerns in the Columbia Basin and Yakima Valley.

  4. Latest satellite heat detections for #GrayFire Spokane County, WA. Large yellow squares are detections by GOES satellite. Some of that data is likely smoke but not fire on the ground - at least yet.

    Never rely on any map to ignore an order to evacuate.

  5. July 31 morning. Interactive #GIS map shows MODIS and VIIRS satellite *heat* detection for #EagleBluffFire near #Oroville WA and #Osoyoos BC.

    Apparently no infrared flight last night.

    Pink area on USA side is clickable and at time of my post shows 9,743 acres as of Saturday evening.

  6. July 30 morning. Interactive #GIS map shows MODIS and VIIRS satellite *heat* detection for #EagleBluffFire near #Oroville WA and #Osoyoos BC.

    Detection data is not real time, locations only approximate and sometimes ‘false positive’. To learn more, click “Map tips” in upper left corner and read about MODIS/VIIRS.

  7. July 29 late afternoon. Interactive #GIS map shows satellite *heat* detection for #EagleBluffFire near #Oroville WA.

    Some heat detections are likely smoke in the air but not fire on the ground (at least yet). But with that said, never rely on any map to ignore an order to evacuate.
