‘Horizontal hurricanes’ – atmospheric rivers pose extreme storm risk but also drought-busting opportunity for California; plans for new 2-3 week forecast and ranking system similar to hurricanesLeave a Comment
- Severe atmospheric rivers in California could mean 23 days of rain and wind causing floods and landslides to the tune of $300 billion in property damage per past USGS modeling
- Atmopheric rivers — while carrying the potential for more damage — will also help California maintain typical rainfall levels amid a drying climate.
- plan to begin publishing regular 14-day to 21-day outlooks on atmospheric rivers as soon as this winter along with new rating system for intensity on a scale of 1 to 5, similar to hurricanes.
…California is facing its own threat of bigger and more destructive storms. Mounting research, much of it done in the wake of the near-record rains that pulled California out of a five-year drought this past winter, shows that seasonal soakers may not come as often as they used to, but could pack more punch when they do arrive.
