Update to our Oct. 29 forecast story and Friday’s shelter update: Baja California’s civil protection office (CEPC) says the weekend storm will be at its strongest on Sunday, Nov. 1. Citing Mexico’s national weather service, the CEPC said heavy rain could fall on Tijuana and the state’s other municipalities through Sunday and possibly into the early hours of Monday, El Imparcial and La Jornada Baja California reported on Friday.
Saturday still brings showers with locally heavy downpours starting around midday, with possible lightning and hail, and the rain could continue into the night, according to the forecast. The CEPC also expects gusts of 50 to 70 km/h (about 30 to 45 mph), waves of 2 to 3 meters along the coast and a drop in temperature, with lows of 0 to −5 °C in the mountains. Most of the state should improve on Monday. La Jornada reported that the storm is driven by the season’s fourth cold front combining with an atmospheric river, a low-pressure trough and the subtropical jet stream.
Tijuana’s fire department issued its own preventive alert, passing on the national weather service’s forecast of 25 to 50 millimeters of rain on Saturday and 50 to 75 millimeters on Sunday, Tijuana en LÃnea reported. Firefighters asked residents not to use charcoal braziers (anafres or braseros) indoors because of the risk of carbon monoxide, to keep storm drains clear, to remove loose objects from rooftops and never to touch fallen cables.
