Surface troughs, combined with the arrival of moisture from the Pacific Ocean and the Gulf of Mexico, favor the presence of heavy rains over Oaxaca and Chiapas.
This Wednesday, the expansion of a pair of surface troughs (low-pressure channels), located along the West, Center, and Southeast, combined with the arrival of moisture from the Pacific Ocean, the Gulf of Mexico, and the Caribbean Sea, favor the presence of rain and downpours in the states of Oaxaca and Chiapas.
It should be noted that these precipitations will be accompanied by thunderstorms, mainly along coastal areas and during the afternoon. This is due to the energy exchange between the surface and the unstable atmosphere.
On the other hand, we have a permanent dry line over the North, fueled by strong winds from the subtropical jet stream. As a result, wind gusts of 50 to 60 km/h are expected, with the possible formation of whirlwinds, dust devils, or tornadoes in Coahuila, Nuevo León, Tamaulipas, and Coahuila and Chihuahua.
These atmospheric conditions are compounded by high-level instability and the arrival of moisture from the Gulf of Mexico, which favor the development of convective supercells with showers and heavy rainfall of up to 50 mm, accompanied by thunderstorms and the possibility of hail, mainly in the states of Coahuila, Nuevo León, and Tamaulipas.
Anticyclonic circulation in the mid-levels of the atmosphere and low water vapor content will keep the atmosphere hot to very hot across most of Mexico, with a heat wave prevailing in regions of Jalisco, Colima, Michoacán, Guerrero, Oaxaca, Chiapas, Nuevo León, San Luis Potosí, Morelos, and Puebla.
Recommendations
Remember to be alert to wind intensity, as a strong gust can put you at risk from falling objects or being thrown as projectiles. The formation of whirlwinds, dust devils, or tornadoes is common. If you find yourself outside during one of these phenomena, seek shelter immediately in a safe place.
Check your weather forecast. During the hot season, health can be affected by heat waves, causing physical effects on the human body such as dehydration, heat stroke, or dizziness. Remember to stay hydrated and avoid going outdoors between 11 a.m. and 4 p.m. If you detect the presence of a thunderstorm, move to a safe place such as a dry room. Avoid being under trees, on sports fields, near bodies of water, or in swimming pools, as these types of places are often prone to lightning strikes.
