Various parts of the island could record heat rates between 102 and 107 degrees Fahrenheit

Much of the island could experience heat indices between 102 to 107 degrees Fahrenheit (ºF) today, Saturday, according to National Weather Service (SNM).

Meteorologist Gabriel Lojero, who works at the SNM, explained that with the arrival of a large mass of dust from the Sahara, the air will become drier and humidity will be limited, so that maximum temperatures will have favorable conditions to see a significant increase. .

“Today the front part has already arrived, which detached itself from the main mass of dust of the Sahara and we will see that there will be less rain and more heat. For the next few days that will be the pattern: dry, foggy and hot weather, "highlighted the expert in an interview with El Nuevo Día .

The weather forecast for today anticipates maximum temperatures between 90 to 92ºF . SNM records show that the maximum temperature record for today is 94 ºF dating from 1980, while the normal would be to see a maximum of 89 ºF.

"You have to see if the record is reached, but we will definitely have highs in the low 90 degrees, because it will be dry, "said Lojero.

The biggest problem will be dust from the Sahara which, he warned, already from this afternoon to night the island will see a significant increase in the amount of particulate. [19659006]

“The main mass, as such, will arrive tomorrow Sunday and will last until Tuesday. The peak of the highest concentration of this dust will be on Monday when even visibility could be reduced to six miles away. But certainly already today we will see that little by little that particulate will arrive, "the meteorologist explained.

It is the most intense dust event in the Sahara that Puerto Rico will have for several years. Last year there was a similar event, but the one expected from tomorrow has a higher amount of particulate matter, according to satellite images, and the models anticipate that they could even go as far as the state of Texas.

" Generally, the Sahara dust season is until mid-August, because we have the high pressure in the central Atlantic that rotates clockwise and transports that dust that comes out of the desert and brings it to the tropical Atlantic and the Caribbean. As the peak of the hurricane season approaches, it begins to weaken and move further north. So the peak of hurricanes is from August to October, because there is not so much dry air and dust from the Sahara, "explained Lojero.

Low probability of rain and problems with reservoirs

Despite the dominance of dust in the Sahara, Lojero indicated that it is possible that some downpours and thunderstorms will be generated in the west and northwest area as of this afternoon due to the influence of a tropical wave that is passing south of the island.

The eastern zone could also receive some precipitation at night, but it will not be significant. In fact, the models establish that rain should not fall more than an inch and a half for that area.

The forecast represents another bad news for the Carraízo reservoir, whose basin is located in the eastern interior of the island, that in none of the past days of this week did its level increase.

The Aqueduct and Sewer Authority reported today that the Carraízo reservoir dropped nine centimeters to locate its level in 38.10 meters of water that maintains it at the level of operational adjustments.

Meanwhile, the rest of the 10 reservoirs dropped their levels, with the exception of the Guajataca reservoir, which increased three centimeters and now has 193.62 meters of water.

The other three reservoirs under observation are Cidra, Patillas and Toa Vaca today recorded 401.37, 62.07 and 147.72 meters of water, respectively.

Meanwhile, maritime conditions remain calm and stable, according to Lojero, with waves between three to six feet. However, there is a moderate risk of marine currents for almost all the beaches around the island.
