Tropical Storm Iselle forms in the Pacific, over 900 km from Baja California Sur and posing no threat to the state

Mexico's National Meteorological Service is tracking the system, which could strengthen into a hurricane, but it is moving away from Mexican territory and will not bring rain to the peninsula's coasts.

Tropical Storm Iselle formed on the morning of Sunday, August 23, in the Pacific Ocean, more than 900 kilometers south of the coasts of Baja California Sur, according to Mexico's National Meteorological Service (SMN), part of the National Water Commission. The agency determined that the system poses no threat to the state or to the rest of Mexico.

The official forecast indicates that Iselle could strengthen into a Category 1 hurricane in the coming hours. However, its projected west-northwest track will keep it away from national territory over the next few days.

Because of its distance and movement, the SMN does not expect rain, strong winds, or high surf along the peninsula's coasts linked to the system's circulation. Even so, the agency said it will continue to monitor its evolution, intensity, and movement.

Iselle shows why Sudcaliforniano authorities stay on alert this time of year: the Pacific tropical cyclone season began on May 15 and ends on November 30, with September and October bringing the most activity to the southern peninsula. A system forming far away does not rule out another developing nearby within days.

As part of its seasonal preparation, the Civil Protection Sub-Ministry of Baja California Sur reported that it is inspecting 169 temporary shelters across the state so they can be opened if a cyclone forces evacuations from high-risk areas. Families living near arroyos, low-lying areas, or hillsides should be the first to identify their nearest shelter before any alert is issued.

Civil Protection advises residents to keep a family emergency plan ready: a bag with documents, water, medicine, and a flashlight; knowledge of their neighborhood's evacuation routes; and to never cross arroyos or fords during rain, even if the current looks weak. In any emergency, the help lines are 911 and, for anonymous reports, 089.

The recommendation for anyone living in La Paz, Los Cabos, or the rest of the state is to rely only on official SMN and Civil Protection advisories, and to avoid spreading unconfirmed forecasts about the track of Pacific systems.
