Los Cabos on Alert: Tropical Storm Alvin Weakens but Brings Dangerous Surf and Rain

Los Cabos, Baja California Sur – Saturday, May 31, 2025, 8:00 AM MST – Tropical Storm Alvin, the first named storm of the 2025 Eastern Pacific hurricane season, continues to influence conditions in Los Cabos and across the southern Baja California Peninsula this morning. While official reports confirm Alvin is weakening and is not a hurricane, residents and visitors are urged to remain vigilant as the storm’s effects, primarily dangerous coastal conditions and rainfall, are still being felt.

According to the latest advisories from the U.S. National Hurricane Center (NHC) and Mexico’s Servicio Meteorológico Nacional (SMN), Tropical Storm Alvin was located south of Cabo San Lucas, moving in a northerly direction. Maximum sustained winds were around 35 mph (55 km/h). Crucially, Alvin is forecast to degenerate into a remnant low-pressure system later today and is not expected to make landfall as a tropical storm.

Despite its weakening status, the most significant impact for Los Cabos right now is the hazardous marine environment. Large swells generated by Alvin are creating life-threatening surf and strong, unpredictable rip currents along the coastline. These dangerous conditions are expected to persist throughout the weekend. Authorities are strongly advising against all water activities, including swimming and surfing, and are urging people to stay away from beaches and rocky shorelines where waves can be unexpectedly powerful. Wave heights of 1 to 3 meters (approximately 3 to 10 feet) are possible along the coast of Baja California Sur.

In response to these conditions, the Port Captaincy in Cabo San Lucas has maintained the closure of the port to small vessels and recreational boating activities as a precautionary measure.

Beyond the coastal concerns, Alvin’s moisture is bringing periods of rain to the region. These showers, which can be heavy at times, offer some relief to the traditionally dry area but also carry the potential for localized flooding, especially in low-lying zones and arroyos (dry riverbeds). Motorists should exercise caution on potentially slick roads.

Protección Civil (Civil Protection) authorities in Los Cabos and Baja California Sur remain active, closely monitoring the situation and reminding the public to stay informed through official channels. They emphasize the importance of heeding safety recommendations. So far, there have been no reports of widespread evacuations or significant damage directly attributed to Tropical Storm Alvin.

The key message from officials is one of caution: while Alvin is not a hurricane and is on its way out, the lingering effects—particularly the dangerous sea state—still pose a risk. Conditions are expected to gradually improve as the remnant low of Alvin dissipates further.

Residents and tourists should continue to monitor updates from official sources like the NHC, SMN (CONAGUA), and local Protección Civil for the very latest information and guidance.
