Get ready… Cold front 10 leaves the first snowfall in Mexico and will hit these states with heavy rains and temperatures below zero

The cold front number 10 It left the first snowfall of the season in Galeana, Nuevo León, which during the night of this November 21st snow began to appear.

Civil Protection of Nuevo León confirmed the first of these events in the Cerro del Potosí and assured that they are maintained in coordination with the personnel of Navigation Services in the Mexican Airspace (SENEAM) for the monitoring of natural phenomenon for the next few hours.

For his part, he National Metereological Service predicts that the frontal system 10 continue with stationary characteristics on the Gulf of Mexico and will interact with a low pressure channel that will extend from lab to the Mexican southeast, these systems will cause intense punctual rains in areas of Chiapas and Tabasco, very heavy rains in Veracruz (south), Oaxaca (east) and Campeche, as well as heavy rains in Yucatán and Quintana Roo.

In turn, the cold air mass associated with the frontal system will continue to generate a very cold to cold environment with frosts at dawn in high areas of the states of the north tablenortheast, east and center of the Mexican Republic, perceiving a cold environment in the mountains of Chihuahua, Durango and Coahuila.

Likewise, the event of “North” very strong with gusts of 60 to 80 km/h and waves of 2 to 4 meters high on the coasts of Tamaulipas, Veracruz and Isthmus and Gulf of Tehuantepecand strong with gusts of 50 to 60 km/h with waves of 1 to 3 meters high on the coast of Tabasco.

At the same time, the cold air mass associated with the system, will tend to modify its thermal characteristics, however, it will continue to cause a strong “North” event with gusts of 50 to 70 km/h and waves of 1 to 3 meters in height on the central and southern coasts of Veracruz and in the Isthmus and Gulf of Tehuantepec, conditions that will decrease during the afternoon.

On Thursday, the new cold front will spread over the northern Mexican territorywill be associated with a polar trough and a cold core vortex, together with the polar jet stream will cause strong gusts of wind of 70 to 80 km/h with possible dust storms in Baja California, Coahuila and Nuevo Leon, as well as strong gusts of wind from 50 to 70 km/h.

The cold air mass that will propel the front will reinforce the environment from very cold to cold with frosts at dawn in northern states of the national territory, with the freezing environment in Chihuahua, Sonora and Coahuila. In addition, at night or early Friday morning, conditions are foreseen for the sleet or snow fall in the mountains of Chihuahua and Coahuila.

What is a cold front?

The cold front is the leading edge of a polar air mass, which causes a drop in temperature in the area where it passes.

This is formed when a cold air mass collides with a mass of hot air, because being denser, the cold air gets like a wedge under the hot air, which generates movement and causes instability in the atmosphere of that area.

During this phenomenon there are drops in temperature, frostsintense winds, strong waves, abundant cloudiness and drizzle.

Most of the cold fronts that affect our country originate near the North Pole. After going through the USA of America, cross the national territory, from the northwest to the southeast and according to the time of the year and its geographical location, can last from three to seven days.

the season of cold fronts in Mexico It goes from September to May, although in our territory its frequency is highly variable, as is its duration, but on average around 58 a year are recorded, most of them within the winter season.

In the period from November to March, the fronts cross the Mexican territory in the Isthmus and receive the name of Tehuantepecos, strong winds that cause thermal anomalies in the Gulf of Tehuantepec. When the polar masses cross the Gulf of Mexico, they give rise to the phenomena known as nortes.

After the passage of cold frontmost likely it will rain, the humidity and temperature decrease and the wind blows more strongly from the north to the south, a little later the sky begins to clear but that is when the new mass of cold and dry air settles , which causes further decrease in temperature.

Recommendations for cold fronts

These are the measures that can be taken to avoid the cold:

1- Get vaccinated against influenza before the winter season.

2- Cover nose and mouth, to avoid direct exposure to environmental contaminants.

3- Wear at least three layers of clothing, preferably cotton or wool.

10- If stoves are used to heat rooms, they must be placed in ventilated places and turned off before sleeping.

11- The boiler and gas installations must be outside the home to avoid leakage.

12- Carry out maintenance in gas installations to avoid the presence of rust that prevents proper combustion and/or leaks.

13- Check that the flame emitted by the stove or boiler is blue and not red.
