By Drooid · · How we work
Core Event: Formation and Projected Track
Late Sunday, a tropical disturbance organized into Tropical Storm Polo off the southwestern coast of Mexico. At the time of formation the system possessed maximum sustained winds near 40 mph (65 kph) and moved east-northeast at about 5 mph (7 kph). The storm was centered roughly 270 miles (435 km) south of Manzanillo and the same distance southwest of Zihuatanejo.
Data & Statistics
- Wind speed: ~40 mph (65 kph) at formation.
- Location: 270 miles (435 km) south of Manzanillo, 270 miles (435 km) southwest of Zihuatanejo.
- Movement: East-northeast at ~5 mph (7 kph), with a turn eastward expected Tuesday and a sharp turn north-northwest Wednesday.
- Rain forecast: Heavy precipitation anticipated for the Mexican states of Michoacán, Colima and Jalisco through Thursday.
- Comparative storms: Simultaneously, Tropical Storm Fay in the northern Atlantic and Tropical Storm Odalys in the Pacific were noted, but both remained far from land.
Official Statements & Responses
According to the U.S. National Hurricane Center in Miami, Polo was expected to strengthen rapidly over the next few days and could become a major hurricane by midweek. The center’s forecast also highlighted the impending directional shifts—an eastward turn on Tuesday followed by a sharp north-northwest turn on Wednesday—driving the heavy-rain threat toward the aforementioned Mexican states.
Potential Impact on Mexico
The projected heavy rain raises concerns for flooding and landslides in Michoacán, Colima and Jalisco, regions that often experience severe runoff during tropical events. While wind speeds at formation were modest, the anticipated rapid intensification could elevate wind-related hazards if the storm reaches major-hurricane status before moving inland.
Context: Broader Pacific Activity
The same period saw the development of two additional tropical systems: Tropical Storm Fay, situated southwest of the Azores with winds near 70 mph (110 kph) but forecast to weaken, and Tropical Storm Odalys, located about 1,350 miles (2,170 km) west-southwest of Baja California’s southern tip and expected to become a hurricane within a day. Both remained distant from land, underscoring Polo as the primary immediate threat to Mexico.
