- Pioneer Fire Soil Water Repellency Demonstration
- Date posted
- 8 years ago
- Description
- Flash flooding, debris and mud flow danger is enhanced around the Pioneer Fire burn scar. Burnt vegetation has altered the soil properties in that the ground is unable to absorb rainfall effectively in portions of the burned area. Without vegetation to hold the soil in place, heavy rain can produce mud and debris flows. When normally dry soil becomes overly saturated, it can reach a point where it turns to a liquid state and flows downhill, essentially becoming a river of mud. Mud and debris flows can destroy homes, wash out bridges and roadways, and knock down trees. They can also deposit large amounts of mud and other debris on previously clear surfaces, damaging or burying everything in their path.

- Turn Around Don't Drown - Public Service Annoucement
- Date posted
- 8 years ago
- Description
- Flooding is one of the leading causes of weather related fatalities in the U.S. On average, flooding claims nearly 90 lives each year. More than half of these deaths occur in motor vehicles when people attempt to drive through flooded roadways. This happens because people underestimate the force and power of water, especially when it is moving.
Just six inches of fast-moving water can knock over and carry off an adult. Twelve inches of water can float a small car. If that water is moving, it can carry that car away. Eighteen to twenty-four inches of flowing water can carry away most vehicles, including large SUVs. It is impossible to tell the exact depth of water covering a roadway or the condition of the road below the water. This is especially true at night when your vision is more limited. It is never safe to drive or walk through flood waters. Any time you come to a flooded road, walkway, or path, follow this simple rule: Turn Around Don’t Drown.

- What is GOES-R?
- Date posted
- 8 years ago
- Description
- The GOES-R series, NOAA's next-generation geostationary weather satellites, is a game changer. These satellites, beginning with the launch of GOES-R on November 4, 2016, will provide continuous imagery and atmospheric measurements of Earth’s Western Hemisphere, total lightning data, and space weather monitoring to provide critical atmospheric, hydrologic, oceanic, climatic, solar and space data. These measurements will lead to significant improvements in the detection and observations of meteorological phenomena that directly affect public safety, protection of property and our GOES fleet in the GOES-R era nation’s economic health and prosperity.

- Description
- A coronal mass ejection occurred June 21. There is a chance we could see the aurora tonight in the Pacific Northwest once it gets dark! Stay tuned! This is the WSA-Enlil Solar Wind Prediction model from the NOAA NWS Space Weather Prediction Center.
WSA-Enlil is a large-scale, physics-based prediction model of the heliosphere, used by the Space Weather Forecast Office to provide 1-4 day advance warning of solar wind structures and Earth-directed coronal mass ejections (CMEs) that cause geomagnetic storms. Solar disturbances have long been known to disrupt communications, wreak havoc with geomagnetic systems, and to pose dangers for satellite operations.
In the movie, the Sun is represented as a yellow dot, the Earth by a green dot, and the STEREO spacecraft by the red and blue dots. The top row represents the WSA-Enlil predicted solar wind density and the bottom row the predicted solar wind velocity. On the left is a pinwheel plot of the ecliptic plane, showin...

- Much cooler weather by Monday

- Description
- Much COOLER weather on the way for Southwest Idaho and Southeast Oregon! A strong cold front will move through the region late tomorrow night into Monday morning. The storm up by Alaska will form a blocking high pressure over Western North America which will allow the jet stream to push cold arctic air southward over our area.
This graphic shows the air mass temperatures with areas of precipitation in grey, blue, and green shading. Air mass temperatures cold enough for snow are where the sky blue colors change to dark blue. The jet stream flows parallel to the white lines and is strongest where the lines are tightly spaced together.

- Nuri controls weather for most of Northern Hemisphere
- Date posted
- 10 years ago
- Description
- Interesting weather pattern for everywhere around us. A strong low pressure in the Bering Sea (Remnants of Typhoon #Nuri) will control the weather for most of the Northern Hemisphere.
What this means for us is drier than normal conditions and above normal temperatures as a ridge of high pressure builds across the West.
If you are wondering where winter is, it will be making an appearance east of the Rocky Mountains starting Sunday over much of the Eastern United States. This graphic shows the air mass temperatures with areas of precipitation in grey, blue, and green shading. Air mass temperatures cold enough for snow are where the sky blue colors change to dark blue. The jet stream flows parallel to the white lines and is strongest where the lines are tightly spaced together.

- Tropical Storm Nuri becoming monster extratropical cyclone
- Date posted
- 10 years ago
- Description
- Relatively benign weather can be expected over the next week as a result of Tropical Storm Nuri perturbing the Jet Stream, building a ridge over the Western United States and our area...with cold weather east of the Rockies. A potentially dangerous storm is forecast for the Bering Sea later this week. The remnants of Tropical Storm Nuri will interact with cold Arctic Air over the Bering Sea of Western Alaska.
Areas in and near the Western and Central Aleutians will likely see the highest wind and waves. Hurricane force wind and seas of 45 to 50 feet are possible Friday and Saturday. Gusts to 100 mph are not out of the question near Shemya and Attu.
