Cancun, Quintana Roo. The State Civil Protection Coordination (COEPROC) forecast a very hot day with scattered showers and lightning across northern Quintana Roo from Friday July 31 through 6 a.m. Saturday August 1, driven by a low-pressure trough over the Yucatan Peninsula and moisture flowing in from the Caribbean Sea.

Maximum temperatures in Benito Juarez will range between 35 and 37 degrees Celsius, while Isla Mujeres may reach 40 degrees with a heat index of up to 43. Lazaro Cardenas is expected to see highs of 37 to 39 degrees and a heat index of 42. Cozumel, Playa del Carmen and Tulum will peak between 32 and 35 degrees.

Rainfall accumulations are projected between 5 and 25 millimeters, with the possibility of electric storms and coastal wind gusts of 40 to 60 kilometers per hour. Wave heights of 3 to 5 feet are expected in the Yucatan Channel and along the northern coast. Civil Protection confirmed no active tropical cyclones in the Atlantic or eastern Pacific as of this Friday.

The agency is also tracking a tropical wave moving from the Cayman Islands toward Panama at 27 kilometers per hour, with no direct impact expected on Quintana Roo in the next 24 hours.

Advice for residents. COEPROC recommends avoiding intense physical activity under the sun, staying hydrated with plain water, wearing light clothing and a hat, and never leaving children or older adults inside parked vehicles. During storms, people should take shelter in solid buildings, stay away from trees and light poles, unplug appliances and refuse to cross flooded streets.

Beachgoers must respect the flags posted by the Harbor Master and lifeguard instructions due to the elevated surf. Drivers should slow down for the possible fog banks in the early morning and late evening as well as for flooded avenues.

How to ask for help. Dial 911 for emergencies. Benito Juarez Civil Protection responds to reports of downed trees, flooding or storm damage at the municipal hotline, while drainage failures can be reported through the City Hall and Aguakan.
