Overview
- The Servicio Meteorológico Nacional said on Thursday that one Pacific low about 660 km southwest of Playa Pérula, Jalisco, has roughly a 40 percent chance of tropical-cyclone development and could be named Douglas if it organizes.
- SMN has issued an official watch and notified Protección Civil to prepare response protocols for coastal hazards including strong winds, high seas and heavy rainfall if the system strengthens.
- Tropical wave 11 interacting with an upper-level trough is producing widespread heavy to very strong rains and thunderstorms with lightning and possible hail across southern, central and western states such as Oaxaca, Guerrero, Puebla, Mexico City, Jalisco and Colima.
- A persistent mid-level anticyclonic circulation is maintaining a heatwave in northern and northwestern Mexico with daytime highs commonly 36–38°C and isolated spots near 40°C, increasing heat-health risks.
- Recent local impacts include a strong hailstorm in Chapela and Teis (Galicia), and regional forecasts warn of flash flooding, gusty winds and electrical activity; officials say conditions can change quickly and urge people to follow SMN and Protección Civil updates.
