Heavy Rainfall and Thunderstorms Across Mexico
April 20 marks the beginning of a rainy week in Mexico, as the National Meteorological Service (SMN) predicts heavy rain, thunderstorms, and possible hail across various regions of the country. Residents are advised to stay prepared as weather conditions are set to become unfavorable.
Weather Conditions Contributing to Heavy Rains
The anticipated rainfall is the result of a combination of low-pressure channels, atmospheric instability, and the influx of humidity. These meteorological factors are expected to cause substantial rain, notably in the central and western parts of Mexico.
Regions Affected by Very Heavy Rains
According to the SMN, very heavy rains (amounting to 50 to 75 mm) are expected in:
- Michoacán (northwest, center, and northeast)
- Guanajuato (south and southeast)
- State of Mexico (west, center, and southwest)
These weather conditions may lead to significant hazards such as flooding and rising river levels, necessitating extreme caution in affected areas.
Showers and Thunderstorms Expected Nationwide
Furthermore, other regions will likely experience showers with heavy rain (25 to 50 mm), including:
- Jalisco
- Queretaro
- Morelos
- Mexico City
- Guerrero
- Oaxaca
- Chiapas
- Veracruz
- Tabasco
Additionally, there will be shower intervals (5 to 25 mm) in northern, central, and southeastern states, including Chihuahua, Coahuila, Nuevo León, Puebla, and Tlaxcala.
Impact of Rain on Urban Areas
All types of rain will be accompanied by lightning strikes and potential hail, which increases the risk for urban areas and roadways. It is essential to adhere to safety protocols during these weather events.
Extreme Heat Continues Amidst Rainfall
Remarkably, even with the predicted rains, much of Mexico will still experience a lingering heat wave. The SMN has reported temperatures soaring as follows:
- 40 to 45°C in Sinaloa, Durango, Nayarit, Guerrero, and Chiapas
- 35 to 40°C in several northern, western, and southeastern states
- 30 to 35°C in areas of the center and the Gulf of Mexico
This stark contrast between extreme heat and intense rainfall is typical for April weather in Mexico.
