Imelda Expected Offshore; Coastal Surf Risks

Across the Desert Southwest, drier air will bring mostly sunny, less humid conditions with valley highs nearing 100°F Thursday–Friday before cooling into the low 90s for the weekend and isolated mountain showers; a trough and Great Basin system will increase southwesterly winds Friday. The Northeast and Mid-Atlantic will be mostly sunny and fall-like, though a strong cold front near Philadelphia will bring gusty north winds, a midweek temperature drop and potential chilly nights with frost risk inland. Tropical systems Imelda (formerly Tropical Depression Nine) and Humberto are forecast to remain offshore and are now expected to pose mainly elevated surf and rip-current hazards rather than bringing heavy rain or landfall impacts to the Carolinas. Overall the nation’s short-term trend is largely dry and seasonally variable, with localized gusty winds and coastal hazards the main impacts to watch. Analysts note a broader rise in severe-weather costs, with Gallagher Re reporting 15 billion-dollar U.S. weather disasters in the first half of 2025.
