Tropical storm Marie could strengthen into a hurricane off Baja California Sur with heavy rain and high surf

State Civil Protection asks all five municipalities to avoid crossing arroyos and to secure roofs and water tanks as the system moves southwest of the peninsula.

Tropical storm Marie could strengthen into a Category 1 hurricane on Wednesday, September 2, as it moves through the Pacific southwest of Baja California Sur, bringing heavy to very heavy rain, high surf and winds of 30 to 40 km/h with gusts of 50 to 70 km/h across the state, according to the National Meteorological Service.

The system is tracking northwest, and its broad circulation will keep swell running against the peninsula's coasts. The state's Civil Protection office renewed its call for residents to rely only on official channels during cyclone season.

Authorities urged specific precautions: do not cross arroyos or low crossings with running water, reinforce roofs and rooftop water tanks, prune weak tree branches and remove loose objects the wind could carry off. The advisory applies to La Paz, Los Cabos, Comondú, Loreto and Mulegé.

Civil Protection noted that the Pacific cyclone season runs from May 15 to November 30 and that 13 of the 18 to 21 forecast systems have formed so far this year, with continued rain expected in the coming days. In Baja California Sur, where the ground is mostly dry and arroyos fill quickly, the leading cause of emergencies during these rains is fast water in channels that stay dry most of the year.

What to do if you live near an arroyo or in a low-lying area: map a route to higher ground in advance, keep documents and a basic kit with water, a flashlight and medication ready, and never try to cross a flowing channel on foot or by vehicle, since a few centimeters of current can sweep away a truck. In an emergency, the national help line is 911.

The state government said it will not spread unconfirmed information and asked residents not to share rumors on social media. Officials recommend following updates from the National Meteorological Service and Civil Protection, which refresh the system's track several times a day.
