Overview
- A large mid‑latitude pattern change arrived Thursday and Friday, bringing cooler temperatures, scattered showers and mountain downpours across the West, Plains and Interior Northeast.
- Forecasters say a nor’easter is becoming more likely this weekend for the Mid‑Atlantic through New England coast, with forecasts calling for strong onshore winds, hazardous surf, and the potential for moderate to major tidal flooding at vulnerable shorelines.
- High‑wind warnings and advisories are in effect in parts of the Pacific Northwest and Northern Rockies with gusts forecast near 40–70 mph, and flood watches target southwestern Colorado where 1–2 inches of rain and high‑elevation snow are possible.
- The National Hurricane Center and regional offices are monitoring Pacific hurricanes Polo and Odalys plus an Atlantic tropical wave off Africa as possible sources of extra moisture that could amplify downpours across the Desert Southwest and southern Plains early next week, though track and timing remain uncertain.
- Officials urge caution: local NWS and coastal offices have issued marine, rip‑current and flood products and say small shifts in storm track or tropical moisture could materially change who sees the heaviest rain or worst coastal flooding, so residents should follow updated watches and warnings.
