The National Hurricane Center reported active tropical formations across both the Pacific and Atlantic basins, prompting marine advisories and regional rainfall monitoring. In the eastern Pacific, Tropical Storms Karina and Lowell formed while tracking northwestward, with meteorologists projecting gradual intensification into hurricane status over subsequent days. Karina positioned itself hundreds of miles south of the Baja California peninsula, generating hazardous swells and life-threatening surf conditions along southwestern Mexican coastal areas. Meanwhile, Tropical Storm Dolly developed in the central Atlantic Ocean carrying modest maximum sustained winds while moving westward toward Caribbean island territories. Forecasters anticipated that atmospheric conditions would induce steady weakening of the Atlantic system before reaching major hurricane thresholds. Regional emergency management agencies across the Leeward Islands, Puerto Rico, and Hispaniola maintained vigilance for potential heavy rainfall and localized flash flooding episodes associated with Dolly's passing moisture plume.
