Ash from Katmai's 1912 eruption is still being resuspended in 2026.

1. Alaska Climate and Aviation Podcast features David Kochevar on aviation forecasting, volcanic ash, and meteorology careers in Alaska. 2. Katie Ryder interviews Kochevar, a NOAA National Weather Service Warning Coordination Meteorologist with the Alaska Aviation Weather Unit in Anchorage. 3. The conversation asks how February's forecasting changes affect pilots and why human meteorologists remain important as AI develops. 4. Kochevar says the Alaska Aviation Weather Unit updated its surface chart and significant-weather chart in February. 5. The significant-weather chart now provides a 24-to-60-hour outlook for Alaska pilots. 6. The changes followed aviation-community feedback that began at the Aviation Gathering in Palmer in 2024. 7. A 90-day feedback period in the fall helped prepare pilots before implementation ahead of the summer flying season. 8. Higher-resolution model guidance improved low-level-turbulence and flight-category forecasts on the newer production system. 9. Shared National Weather Service data improved the current surface chart's resolution and frontal information. 10. Kochevar directs listeners to weather.gov/awu for Alaska aviation forecasts, graphics, observations, satellite data, and radar data. 11. Kochevar traces his aviation-weather interest to McGrath, where he spoke with pilots near the local flight service station. 12. His career included Iowa State, Anchorage's FAA center weather service unit, the Anchorage forecast office, and National Weather Service regional headquarters. 13. Kochevar says aviation connects remote Alaskan communities to medical appointments, food deliveries, and school basketball games. 14. The Alaska-Pacific River Forecast Center publishes breakup forecasts at weather.gov/aprfc and identified potential flooding risk for major rivers. 15. Kochevar says breakup flooding depends on how quickly temperatures rise when river ice begins breaking up. 16. The Anchorage Volcanic Ash Advisory Center serves as an initial warning office for eruptions near Alaskan airspace. 17. Kochevar says satellite observations and Alaska Volcano Observatory analysis identified Katmai ash from 1912 still being resuspended in 2026. 18. The interview uses a conversational question-and-answer format, moving from chart changes to public services, volcanic hazards, and AI. 19. Alaska pilots and weather-service career seekers. 20. Listeners uninterested in aviation or meteorology careers.
