Isla Mujeres, Quintana Roo — The Port Authority reopened minor navigation at the ports of Isla Mujeres and Puerto Juárez, allowing vessels under 40 feet in length to navigate after restrictions were applied by local and regional Port Captaincies on Friday for the safety of boats of that type.

Both ports had remained closed on Friday, October 16, to vessels smaller than 40 feet, as well as to coastal fishing, sport fishing and snorkeling activities. The closure was due to southeast winds of 27 to 29 km/h with gusts up to 31 km/h and waves of 0.30 meters, according to notice GOLF 04-161026 from the Port Captaincy of Isla Mujeres.

Heavy Rain and Electrical Activity Forecast

The National Meteorological Service (SMN) said heavy rains with isolated very heavy downpours of 50 to 75 mm accompanied by electrical activity are expected this Saturday in Quintana Roo. The conditions were attributed to Cold Front number 2, low pressure troughs and the entry of moisture from the Caribbean Sea and Gulf of Mexico.

For the Isla Mujeres-Cancun area, forecasts call for partly cloudy to cloudy skies, hot conditions, maximum temperatures of 29° to 30°C and a heat index of up to 35°C due to humidity. Minimum temperatures are expected to be 25°C to 27°C at night. East and northeast winds are forecast at 10 to 20 km/h with gusts of 30 to 50 km/h, along with waves of 0.9 to 1.5 meters in Bahía Mujeres and 1.2 to 1.8 meters on the Caribbean coast.

Similar Conditions Expected Sunday

For Sunday, October 18, the forecast indicates similar conditions, with partly cloudy skies, isolated showers and scattered thunderstorms, a 40% chance of rain, maximum temperatures of 30°C, minimum temperatures of 26°C and east-northeast winds of 9 to 15 km/h.

The Port Authority and Civil Protection recommended that sailors, fishermen and tourism service providers stay alert to official warnings and take extra precautions due to reduced visibility and electrical activity at sea.
