The Bruler fire continued into August as warm and dry conditions persisted.
Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.

NWS Portland, OR wrote its last area forecast discussion before the first event at Jul 31, 8:07 PM PST, 3 hours 53 minutes earlier.
Area Forecast Discussion...Updated National Weather Service Portland OR 907 PM PDT Sat Jul 31 2021 Updated Aviation .SYNOPSIS...Little change in the forecast as high pressure persists over the area. A weak shortwave with monsoonal moisture will bring showers to much of the area and a slight chance for thunderstorms along the central Oregon Cascades. Above normal temperatures expected through the middle of next week. && .SHORT TERM...Tonight through Monday night...A very dynamic system comprised of high pressure over eastern Oregon and a nearly stationary low pressure system near the Alaska Panhandle. Aloft, the jet stream (at around 35,000 ft or 250mb), shows a jet max over the area which is enhancing the already present monsoonal moisture in place. The combination of these two factors, along with warm air at the surface, is bringing widespread showers to the area that never really ended from last evening. The highest rainfall rates have been along the north Oregon/south Washington coasts and along the south Washington Cascades. Radar does indicate some rain to the south, however little is reaching the ground as it is falling as virga. Satellite shows widespread cloud cover that did not dissipate this afternoon which has kept temperatures closer to normal in the low 80s throughout most of the inland portions of the forecast area. Still experiencing some breaks, especially in the southern Willamette Valley, but those few breaks will have minimal impact on drastic temperature increases. These clouds have also hindered thunderstorm development due to a lack of diurnal heating, and thus less convective motion. There is still a chance that we could see a lightning strike or two this afternoon/evening, but likely would be isolated to the central Oregon Cascades right along the crest. At the rate conditions are going, not expected to move too far west into the Willamette Valley. On Sunday, conditions will begin to dry as the ridge strengthens and tilts westward. This will cut off more of that moisture from the CONUS south, and allow the upper atmosphere to dry. In addition, the jet stream will migrate away from the area to the north which will eliminate the upper level support necessary for the precipitation. Less cloud cover is expected on Sunday which will allow temperatures to rise more than today. Expecting high temperatures in the low to mid 90s. With the moisture remnants from the precipitation today, there is a very slight chance for some thunderstorms along the southern most portions of the Willamette Natl. Forest. Confidence is incredibly low so have isolated to the Cascade Crest. Monday brings a bit more activity with a shortwave passing through the flow at 500mb. This shortwave will bring a burst of energy to the region and encourage convection. Latest model runs have delayed the shortwave advancement slightly, but it's impacts are still likely to start on Monday. Expecting showers again the southern portions of the forecast area along with another round of slight chances for thunderstorms. Long range models are showing around a 25% chance for thunderstorms on Monday afternoon throughout the Lane County Cascades and foothills. Have decided to expand this chance a bit further west and north into the southern Mt Hood Natl. Forest. There is still a bit of uncertainty with the track and timing of this shortwave so will continue to monitor with future model runs. -Muessle .LONG TERM...Tuesday through Friday...By Tuesday, the shortwave will have passed and the lower levels of the atmosphere will once again dry. Not expecting any significant weather on Tuesday, but may see a very slight chance for some lingering showers through the morning. Wednesday though is another story. Long range models continue to hold on to another shortwave trough advancing northeast over the region starting Wednesday evening. This shortwave extends from the parent nearly stationary low that will continue to spin near the Alaska Panhandle. This system has significantly more energy and moisture than the wave expected on Monday. Based on current depictions of the track, this disturbance should make landfall Wednesday evening through Thursday. If the timing and strength rings true, could see a chance for widespread rain showers, but will little accumulation. Have increased PoPs through the southern Willamette Valley to around 15% as there is a chance that those areas could see periods of showers. This shortwave is just the opening act to the low near the Alaska Panhandle dropping down southward along the US/Canada border. Will note though that this whole pattern shift will be strongly dependent on how extensive the ridge builds back in. If the ridge intensifies it may be enough the keep the shortwave well offshore and thus, missing us completely. Based on decent long-range model consensus and cluster analysis though, trending towards a cooler and wetter mid next week...fingers crossed. -Muessle && .AVIATION...04z update: Showers have mostly tapered off across the area, but with plenty of lingering mid/high level cloud cover. Still expecting VFR at all inland terminals through Sunday. Coastal sites have seen some variation in flight categories as marine layer starts to fill back in this evening. Expect stratus to settle in by around 06z and bring IFR/LIFR conditions to KAST and KONP into Sunday morning. Monday should bring VFR and thinning cloud cover across most of the area as shower activity remains mostly limited to the central OR Cascades. For detailed regional Pac NW aviation weather information, go online to: https://weather.gov/zse KPDX AND APPROACHES...VFR expected through Sunday evening, with just some mid/high level cloud cover overnight starting to thin out on Monday. /CB && .MARINE...Still have stronger high pres well offshore, with lower pres well inland, as well as the thermal trough over far southwest Oregon. This will maintain the northerly pres gradient across the coastal waters for next several days. But, gradients will tighten a bit on Sun, with afternoon northerly winds gusting 20 to 25 kt on the outer waters, especially south of Cascade Head. Strongest winds will be in the afternoons/evenings. Will put up small craft advisory for the outer waters, starting Sun afternoon. Pattern does not shift much, with gusty north winds still likely on Tue, perhaps even across the inner waters (with 10 nm of shore). Later in the week, models show a weakening trough moving to the waters Wednesday into Thursday to shift winds to the west then southwest. This system is attempting to push into the strong high pressure inland, so it could weaken further and/or be delayed with later model runs. Seas remaining in the 4 to 6 ft range, mainly driven by wind waves and a small westerly swell. -Rockey && .PQR WATCHES/WARNINGS/ADVISORIES... OR...None. WA...None. PZ...Small Craft Advisory for Sunday afternoon through Monday evening on outer waters (10 to 60 nm offshore) from Cape Shoalwater to Florence. && Interact with us via social media: www.facebook.com/NWSPortland www.twitter.com/NWSPortland
