On Thursday, rains fell in some parts of Mexico, especially in Jalisco. This was because, according to the National Meteorological Service (SMN), cold front 55 remains stationary to the north of the Gulf of Mexico, which favors the entrance of humidity and favors rainfall from Tamaulipas to Tabasco. Also, a line of low pressure and humidity will favor rain showers in Chihuahua, Durango, and Zacatecas. And finally, high temperatures continue in most of the country, although rain is probable in Jalisco. However, more than a few people are wondering, when does the 2021 rainy season begin?
According to the website meteored.mx, statistically, the tropical cyclone season begins on May 15 in the northeastern Pacific basin, while in the Atlantic it begins on June 1, ending on both coasts on November 30. The dates do not change; however, the rains may begin earlier or later. In Mexico, they point out, although there is no specific day on which it will start raining, precipitations begin regularly in the second half of May, settling in June, when tropical waves, cyclones, and humidity inflows fully affect the country.
According to the forecast of meteored.mx for May 2021, rainfall will behave relatively normally, that is, accumulations of 10-60 mm above the climatology are probable in the central, western, southern and eastern states, such as Jalisco, Michoacán, Colima, Guanajuato, Guerrero, Zacatecas, San Luis Potosí, Querétaro, Hidalgo, State of Mexico, Mexico City, Tlaxcala, Morelos and Tabasco, while in Oaxaca, Veracruz and Chiapas there may be rainier conditions exceeding 60-90 mm above normal. On the other hand, in northern entities and the Yucatan Peninsula, rainfall may be very low.
Knowing the date when the 2021 rainy season begins allows us to take mitigation measures in time to avoid dangers, such as floods, so it is advisable to carry out the maintenance of streets, and above all, of homes, to avoid incidents.
