Puerto Vallarta, Jalisco, Mexico - According to one expert, this morning's scattered thunder showers were just a preamble to what is expected to be a strong rainy season in the Banderas Bay region.

The head of the meteorological department at El Centro Universitario de la Costa (CUC), Victor Manuel Cornejo, says that the rainy season in this area of the Pacific is about to begin and there's a strong possibility that Puerto Vallarta is in for some stormy weather for the remainder of this month and all of July.

The meteorologist said that the rainy season will get off to a strong start over the next eight weeks. He said there's a possibility of a short break in early August, but the rains are expected to return in late August and continue on a regular basis through the middle or end of October.

For now, he said, every day is getting more and more humid in the Banderas Bay area, and this moisture is consolidating into the first of the summer's heavy rains.

In this sense, he calls upon the general population to remain vigilant and to carry out preventive maintenance in and around the home as soon as possible, as strong flood waters from the mountains are anticipated.

Cornejo stressed the importance of ensuring that garbage does not accumulate on the streets, because when there is moderate to severe flooding in the city's neighborhoods, waterlogged waste is one of the biggest health hazards.

He noted that civil protection has already been activated and the respective council is in permanent session, both of which are monitoring weather conditions to issue the corresponding recommendations as required.

The rains, Cornejo warned, are just around the corner, and that the combination of heavy storms and the temperature of the ocean rising every year is "pure fuel for hurricanes," so everyone should stay aware of the formation and trajectory of these phenomena.

Moreover, he said, average maximum temperatures in June and July could exceed those in most of the country, and could intensify in the late July, in respect to normal temperatures in the northern and southern parts of the country.

Similarly, in August a significant increase in the monthly average maximum temperatures is forecast for the northeast, south and southeast of the country, although temperatures in the country's center are expected to decline.

He revealed that according to weather statistics from 1981 to 2010, in June monthly average maximum temperatures of above 35°C (95° F) have been recorded, mainly in Baja California, Sonora, Chihuahua, Coahuila, Nuevo Leon, Tamaulipas, Sinaloa and Nayarit.

In fact, it is estimated that in June, the monthly average temperature will be above average in most of Mexico, especially in regions of Jalisco and northern Sonora, Chihuahua, Coahuila, Durango, Sinaloa and Tamaulipas, as well as in Guerrero, Oaxaca and Veracruz.
