Sahara dust: Meteorology warns that its concentration will increase tomorrow


The National Weather Service (SNM) in San Juan warned today, Thursday, the dry air mass with sahara dust that affects the island will increase its concentration during the day tomorrow until the weekend, so asthmatic and allergic people should take precautions.

“We have moderate concentrations today and tomorrow. But tomorrow we will have a new pulse of this particulate that will increase the concentration “, forecasted meteorologist Ernesto Rodríguez to The new day.

The Saharan dust cloud seen in satellite images extends from the Lesser Antilles to the west of the Sahara Desert in Africa.

However, satellite images show a drier and denser air mass of dust particles near Africa.

For now, the models do not anticipate that the next haze episodes will be the same as the historic event that affected the island last June 2020. At that time, the dust cloud from the Sahara was so dense and wide that it reached the Cancun area in Mexico.

Dust from the Sahara has remained in the region since last Monday when the first extensive cloud arrived from West Africa. From that moment the air quality remains at a moderate level, according to the station of the Environmental Quality Board in Cataño.

Before that, The SNM urged asthmatics and allergy sufferers to take precautions and their prescribed medications to avoid health complications.

Rodríguez indicated, in turn, that the haze episode that affects the region will limit the formation of rains and promote warmer conditions.

“We will have a hot day not only because of the dust from the Sahara, but also because of the wind blowing from the south-southeast and that will raise temperatures. We expect a temperature of 93 degrees Fahrenheit ”, the expert pointed out.
