Heat up to 40 °C and thunderstorms this Sunday across northern Quintana Roo
State Civil Protection forecasts a heat index of 45 °C in the northern zone, with 25 to 50 mm of rain, lightning and coastal wind gusts up to 40 km/h.
Northern Quintana Roo faces a very hot Sunday, August 9, with highs of 36 to 38 °C in Benito Juárez and up to 40 °C in Lázaro Cárdenas and Isla Mujeres, plus strong showers with lightning, according to the weather bulletin issued by the state Civil Protection coordination (COEPROC), valid from 6:00 a.m. today through 6:00 a.m. Monday.
The agency reports that moisture flowing in from the Caribbean Sea and an upper-level trough will bring partly cloudy skies with increasing cloud cover through the day. In the northern municipalities the heat index could reach 45 °C, and estimated rainfall ranges from 25 to 50 millimeters, with easterly winds of 15 to 25 km/h gusting to 40 km/h along the coast.
Elsewhere in the state, Civil Protection expects 34 to 36 °C in Playa del Carmen, 35 to 37 °C in Puerto Morelos with showers, and rain with intervals of showers in Tulum, Felipe Carrillo Puerto, Othón P. Blanco and Bacalar. Waves are forecast at 2 to 4 feet in the Yucatán Channel and along the coast, with sea temperatures of 28 to 29 °C. The bulletin itself notes that no tropical cyclones are active in the Caribbean.
What to do today. COEPROC recommends avoiding intense physical activity under the sun, drinking water constantly, wearing light clothing, sunscreen and sunglasses, and driving carefully due to possible fog banks overnight and before dawn. During electrical storms, the safest option is to shelter indoors and never under trees or metal structures.
Local context. Extreme heat and afternoon storms are typical of August, one of the most active months of the Atlantic hurricane season, which runs through November 30. Although no cyclones are being watched near Quintana Roo today, it is a good time to check your emergency kit and keep 911 handy. If a downpour floods your street, avoid crossing running water on foot or by car: most urban rain-related accidents happen at flooded crossings.
