Mexico City activated a yellow alert for low temperatures in six alcaldías (boroughs) for the early hours of Sunday, Nov. 15, with lows forecast between 4 and 6 degrees Celsius. The coldest stretch is expected from 04:00 to 08:00, when the alert is in force.

The warning came from the Secretaría de Gestión Integral de Riesgos y Protección Civil (SGIRPC, the city’s risk management and civil protection agency), which issued it on the afternoon of Saturday, Nov. 14, according to El Economista. The agency asked residents in the affected areas to take precautions to protect their health.

Which boroughs are under the alert

The alert covers six boroughs, mostly in the higher parts of the city’s south and west, where RÉCORD and El Economista say the cold is expected to be sharpest overnight and in the morning:

  • Álvaro Obregón
  • Cuajimalpa de Morelos
  • La Magdalena Contreras
  • Milpa Alta
  • Tlalpan
  • Xochimilco

RÉCORD reported that thermometers in these boroughs could fall as low as 4 degrees, and that the alert runs through the predawn hours and the morning of Sunday until 08:00.

What it means for residents

A yellow alert is a preventive warning. It tells people that the cold could affect their health, and the people most exposed are those who leave home before 08:00 or plan outdoor activity on Sunday morning. RÉCORD said the authorities paid special attention to residents heading out in the first hours of the day.

The SGIRPC said its guidance is meant to reduce health risks and prevent respiratory illness during the cold snap. It also asked people to keep up with official channels for any change in the forecast.

What the SGIRPC recommends

The agency’s list of measures, as reported by the three outlets, includes:

  • Wearing at least three layers of clothing, preferably cotton or wool
  • Covering the nose and mouth so cold air is not breathed in directly
  • Avoiding sudden changes in temperature
  • Drinking plenty of water and eating fruits and vegetables rich in vitamins A and C
  • Using cream to protect and moisturize the skin
  • Washing hands often or using antibacterial gel
  • Bringing pets indoors and not leaving them outside
  • Not using anafres (charcoal braziers) or combustion heaters in closed spaces, and keeping homes ventilated when using heaters or fireplaces
  • Going to the nearest health center if symptoms appear

The warning about heaters and fireplaces is meant to prevent incidents at home, El Universal reported. Its advice on hydration and vitamins A and C appeared in all three reports.

Emergency numbers

City authorities reminded residents that they can call 911 in any emergency, or the number 55 5683 2222, El Economista reported. The SGIRPC said it keeps issuing preventive notices to inform the public about weather conditions that could pose a risk in Mexico City.
