Seattle Weather Forecast: Sun Before Showers and a Cooling Trend

Seattle summer lovers, make the most of today’s sunshine! A shift is on the horizon as forecasters predict a change from warm, sunny skies to potential showers and a cooling trend. This transition, while potentially dampening spirits, brings a silver lining: a reduced risk of wildfires in the region. With temperatures expected to remain cooler than average through Tuesday, residents should prepare for a noticeable change in the weather pattern. The National Weather Service has issued warnings for thunderstorms and potential fire hazards, urging caution and preparedness.

This article will delve into the specifics of the approaching weather system, providing insights into the expected temperatures, rainfall, and potential impacts. We will also examine the red flag warning issued for the Eastern Cascades and the ongoing efforts to combat the Bear Gulch fire in Olympic National Forest. Stay informed and prepared as we navigate this shift in Seattle’s weather.

Enjoy the Sun Before the Showers

Seattle residents are encouraged to soak up the sun today as temperatures climb into the low 80s. However, this warmth is fleeting, as cloudy skies and a cooling trend are expected to begin tonight. There’s a possibility of light rain showers drifting from the Cascades and over the Puget Sound region. According to the National Weather Service, temperatures are expected to remain approximately 5 degrees cooler than average through Tuesday. This shift marks a significant change from the recent warm and dry conditions that have prevailed throughout the summer.

Jacob DeFlitch, a meteorologist at the National Weather Service, notes, “We certainly do need it. We’ve been on the drier side for the last month, and we’re in peak wildfire season, so any rain we would get would be a benefit to dampen those fire weather concerns. But I also love summer, so I understand.” This sentiment captures the mixed feelings surrounding the changing weather, as the need for rain to mitigate fire risk is balanced with the desire to prolong the summer sunshine.

Cooler Weather’s Silver Lining: Decreasing Fire Risk

While the prospect of cooler, wetter weather may not appeal to everyone, it brings a significant benefit: a reduction in the region’s fire risk. The recent dry conditions have elevated concerns about wildfires, making the arrival of rain particularly welcome. The light rain expected over the coming days will help to dampen vegetation and reduce the likelihood of new fires igniting. This is especially crucial as the region remains in peak wildfire season, and any amount of precipitation can make a substantial difference in mitigating potential fire hazards.

The National Weather Service has emphasized the importance of this change, highlighting the positive impact that even light rainfall can have on the overall fire risk. The combination of cooler temperatures and increased moisture will create a more favorable environment, reducing the chances of both new fires starting and existing fires spreading rapidly. This provides a much-needed respite for firefighters and communities at risk.

Red Flag Warning Issued for Eastern Cascades

The National Weather Service has issued a red flag warning for the Eastern Cascades, in effect between 11 a.m. and 8 p.m. today. This warning indicates that some possible thunderstorms and lightning, coupled with hot, dry, and windy weather, could either start fires or cause flames from new and existing fires to spread rapidly. Temperatures in the Eastern Cascades could climb up to 90 degrees, with wind gusts reaching up to 50 mph. These conditions pose a significant threat, making it crucial for residents and visitors to exercise extreme caution and adhere to all fire safety regulations.

The combination of lightning strikes and strong winds creates a dangerous scenario, as any new fires that ignite could quickly escalate and spread uncontrollably. The red flag warning serves as a reminder of the ever-present fire risk during the summer months and the importance of taking proactive measures to prevent wildfires. Authorities are urging everyone to avoid activities that could spark a fire and to report any signs of smoke or flames immediately.

Bear Gulch Fire Spreads in Olympic National Forest

The warm and dry weather has allowed the human-caused Bear Gulch fire, located on the north side of Lake Cushman in Olympic National Forest, to spread significantly. The fire has climbed steep slopes and spread through the tree canopy since it was first spotted on July 6. As of the latest update, the fire has consumed nearly 2,000 acres and is less than 10% contained, according to the National Park Service. Firefighters are working diligently to contain the blaze, but the challenging terrain and weather conditions have made their efforts difficult.

The Mason County sheriff’s office has issued a Level 3 evacuation order for anyone living or camping near the Dry Creek Trail, including the Staircase Campground and areas north of Lake Cushman, instructing them to leave immediately due to the fire danger. Additionally, a Level 1 order has been issued for people south of Dry Creek, warning them to prepare for a possible evacuation. The smoky, hazy conditions caused by the Bear Gulch fire are expected to continue to be noticeable in the Olympic Peninsula, although the air quality isn’t expected to worsen significantly today.

Flash Flood Watches Issued for Burn Scars

Due to the possibility of thunderstorms, flash flood watches have been issued for burn scars throughout the Cascades. Wildfires have left the soil unstable and prone to collapsing in these areas, increasing the risk of flash floods. The flash flood watches include the Bolt Creek burn scar along U.S. 2, where 10,000 acres were charred near Baring and Skykomish in 2022. Watches also cover burn scars in the North Cascades near Sourdough Mountain, Easy Pass, and the Chilliwack area; in Mt. Baker-Snoqualmie National Forest by the Suiattle River and Boulder and Toketie lakes; and in the Goat Rocks Wilderness in Lewis County.

Residents and visitors in these areas should be aware of the potential for flash floods and take necessary precautions. This includes avoiding areas prone to flooding, monitoring weather updates, and being prepared to evacuate if necessary. The combination of unstable soil and potential thunderstorms creates a hazardous situation, and vigilance is crucial to ensure safety.

Stay Prepared for Seattle’s Changing Weather

As Seattle transitions from sunny skies to potential showers and a cooling trend, it’s essential to stay informed and prepared. The approaching weather system brings both challenges and benefits, from the possibility of thunderstorms and flash floods in burn scar areas to a welcome reduction in fire risk. By staying updated on the latest forecasts and heeding the warnings issued by the National Weather Service, residents can navigate these changes safely and effectively.

The shift in weather also serves as a reminder of the dynamic nature of the environment and the importance of preparedness in the face of changing conditions. Whether it’s enjoying the last moments of sunshine or preparing for potential rainfall, being aware and proactive is key to making the most of Seattle’s summer weather.
