Hazy Skies and Diminished ‍Air Quality Expected in Western Washington This ‌Weekend

SEATTLE — As ⁣western Washington prepares‌ for a weekend marked by soaring temperatures, residents​ are also bracing for a decline in air quality due to wildfire smoke from neighboring ⁢Oregon. The Seattle area is experiencing ‌a shift in air quality ratings, moving from “good” ⁣to ‍”moderate”​ as temperatures are predicted to near 90 degrees ⁣throughout the weekend. This change raises concerns for sensitive groups, as the Air‌ Quality Index (AQI) is forecasted to remain in the moderate range ⁤until Monday.

Understanding the ⁤Air ‍Quality Index

The AQI is ‌a crucial measure ⁤of air quality, helping individuals‍ assess​ their exposure to air pollutants. According to IQ Air, ⁤on ⁣Friday morning the AQI for Seattle was recorded at 58, with predictions indicating ⁤a rise to 66 on Saturday and 73 on Sunday. An⁢ AQI reading between 51 and 100 falls into the “moderate” category, suggesting those who are sensitive should limit outdoor ‌activities.

  • Seattle AQI Forecast:
    • Friday: 58
    • Saturday: 66
    • Sunday: 73

Wildfire Smoke and⁤ Heat Advisory

In addition to the heat, the National Weather Service (NWS) issued an air quality alert for Lewis County⁣ until noon Saturday due to smoke from wildfires. The advisory cautions⁢ that “all sensitive groups should limit spending any time ⁤outdoors”⁣ as symptoms may worsen for⁤ individuals with pre-existing health conditions. Meteorologists have observed that the smoke, combined with a heat inversion, ​is exacerbating air quality issues,​ particularly in Pierce County where AQI levels could exceed 100, indicating unhealthy conditions for sensitive groups.

Heat Wave Conditions

The ‌ongoing‌ heatwave is causing daily temperature records to ⁤be shattered in several areas, including Seattle, SeaTac, Olympia, ⁣and Quillayute. A Heat Advisory remains⁤ in⁢ effect for much of western Washington until 11 p.m. on Friday.‍ During this period,⁢ individuals without effective cooling⁢ resources or ⁢adequate hydration are at a moderate risk for heat-related illnesses.

Temperature Trends

Forecasts suggest that Tacoma will also experience highs ​around 90 degrees,‍ leading⁢ to an uncomfortable combination of heat ‌and smoke. However, an eventual cooling trend is ​expected as northwesterly winds from Canada bring in fresher air. ⁤Saturday’s high temperatures are projected to drop to⁤ the 85-88 ​range, followed by further decreases on Sunday, which may ‍see highs around 80 degrees.

The Impact of Heat Inversion

The current weather phenomena includes a temperature inversion, which is ⁣trapping polluted air close to the ⁤ground. Normally, hot air rises, dispersing pollutants; however, these inversions can lead to an⁤ accumulation ​of unhealthy particles. NPR has​ noted that not as much smoke from the‍ Oregon wildfires​ is settling down to ground‍ level, although it remains a concern, particularly around⁤ areas such as Mount Rainier.

Local Health Advisory

As temperatures and ​smoke combine to create subpar air conditions, the Puget Sound Clean Air Agency has advised individuals with respiratory issues‌ or other sensitivities to remain indoors, particularly in Pierce County and the Cascade foothills, where conditions may achieve “unhealthy” ratings at times.

Looking Ahead: Weather Changes ‍on the Horizon

Residents can expect significant shifts‍ next week as a cooler pattern approaches, bringing with it highs in ⁤the 70s and a chance of showers. These changes may improve air quality, ⁤allowing the region to transition from the oppressive heat and smoke levels that currently linger over western Washington.

As the weekend⁤ progresses, it is crucial for residents to stay informed about local air quality updates and weather changes⁣ to protect their health and well-being.
