MIAMI (AP) — Tropical Storm Priscilla was strengthening slowly in the Pacific Ocean off the coast of Mexico early Sunday. The Miami-based National Hurricane Center reported that Priscilla is classified as a “large tropical storm,” with tropical storm-force winds extending up to 140 miles (220 kilometers) from its center. Currently, its maximum sustained winds are recorded at 65 mph (100 kph), and it is situated approximately 305 miles (495 kilometers) south-southwest of Cabo Corientes, moving northwest at 5 mph (7 kph).

A tropical storm watch has been issued for parts of the southwestern Mexican coast, specifically from Punta San Telmo to Punta Mita, indicating possible tropical storm conditions as early as Sunday through Monday. Authorities warn of potential rainfall up to 6 inches (15 centimeters) and life-threatening surf and rip current conditions along the coast.

Forecasts suggest that Priscilla may achieve hurricane status by Sunday night or early Monday and is expected to continue moving parallel to the coast in the coming days.

In addition, another tropical storm named Octave is present in the Pacific, located far from the shore with no expected landfall or coastal warnings. Octave's maximum sustained winds have registered at 70 mph (110 kph), but it remains largely stationary.
