This Tuesday night, the cold front 12 has arrived in the national territory and although it will pass quickly through the country, its polar air mass will leave very cold climateWho? temperature between -10 and -5 degrees, Also strong frost in northern Mexico part of Saltas rain and hail Also in the center and south north event In Isthmus and Gulf of Tehuantepec, it is as predicted National Meteorological Service From National Water Commission.
cold front 12 will move rapidly to the northeast of the country, and interact with a low pressure channel Located east of the Mexican Republic, both systems will cause intense rain Veracruz and San Luis Potosí and very strong in Tamaulipas, Puebla, Hidalgo and OaxacaWhich will be accompanied by lightning discharges and can raise the level of rivers and streams, as well as cause landslides and floods in low-lying areas of said entities.
Similarly, cold air masses that drive forward in interaction with the subtropical jet stream will generate winds of up to 60 km/h. Chihuahua, Coahuila, Durango, Nuevo León, Tamaulipas and AguascalientesAlong with the northern phenomenon and gusts of 70 to 90 km / h Isthmus and Gulf of Tehuantepec.
get ready… Two cold fronts bring snow, sub-zero temperatures and rain to Mexico this week
For tomorrow Thursday, the frontal system will be located to the north with stationary features gulf of mexicowill interact with a low pressure channel that will extend west of the aforesaid Gulf, causing heavy rain veracruz and showers in Oaxaca, Chiapas and TabascoThese showers may be accompanied by lightning discharges.
Similarly, the cold air mass that spawned the aforementioned front will cause northerly winds of up to 50 km/h along the northern coast of Tamaulipas, It is hypothesized that during dusk-night it begins to modify its thermal characteristics.
during friday and saturday sistema frontal 12 It will continue over the Gulf of Mexico and in association with a low pressure channel southeast of Mexico and moisture penetration from the Caribbean Sea and Gulf of Mexico will bring heavy to very heavy rain to the southeast. mexican republicincluding the Yucatan Peninsula.
In addition, the mass of cold air that was attached to the system would modify its thermal characteristics, leading to a gradual rise in daytime temperatures; However, in the northern and central mountains of the national region, the cold weather will continue in the morning. Similarly, a northern component wind will persist Isthmus and Gulf of Tehuantepec.
ingress of moisture from Pacific Ocean and a low pressure channel will spread over the country’s interior and create conditions for rainy with intervals of rain that may accompany Electrical discharges in the northwest, west and center of Mexico.

What is cold front?
cold front It is the front of a polar air mass, which causes a drop in temperature in the region it passes through.
It is formed when a cold air masses As the mass of warm air collides, being more dense, the cooler air becomes wedge-like under the warmer air, which creates momentum and creates instability. climate of that area.
During this incident, Drop in temperature, frost, strong winds, strong waves, abundant clouds and drizzle.
mostly cold fronts Those that affect our country, originate near the North Pole. After crossing the United States, they cross national territory from northwest to southeast and depending on the time of year and their location. Geographically, they can last from three to seven days.
weather of cold fronts In Mexico it goes from September to May, although in our region its frequency is highly variable, as is its duration, but an average of about 58 are recorded per year, most in the winter season.
In the period from November to March, fronts cross the Mexican territory across the isthmus and are called 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 phenomena known as nortees.
after passing cold frontMost likely it will rain, the humidity and temperature will decrease and the wind blows more strongly from north to south, after a while the sky starts to clear but only then a new mass of cold and dry air accumulates, due to which Another decrease in temperature.
Recommendations for cold fronts
These measures can be taken to avoid cold:
1- Get the influenza vaccine before the winter season.
2- Cover nose and mouth to avoid direct contact with environmental pollutants.
3- Wear at least three layers of clothing, preferably cotton or wool.
