Due to the prevailing trough or extended cloudiness of the low pressure area (LPA), the CARAGA and Davao Regions will experience cloudy skies with light to moderate rains and isolated thunderstorms. According to PAGASA Weather Forecaster Jun Galang, the said LPA has a slim chance of entering the boundary. However, continuous monitoring will be done by the weather bureau.

Meanwhile, the ridge or the extended part of the high pressure area (HPA) continues to affect Northern Luzon, bringing partly cloudy to cloudy skies over the regions of Cagayan Valley, Cordillera and Ilocos. Metro Manila and the rest of the country will have generally fair weather aside from possible isolated rain showers or thunderstorms mostly in the afternoon or evening.

To understand these prevailing weather systems, winds in a high pressure are associated with good and sunny weather. Fewer clouds are seen over the affected areas, thus, less chances of precipitation.

On the other hand, winds in a low pressure area are associated to rainy weather due to the presence of more clouds. LPA can form into a tropical cyclone or “bagyo” once it accumulates warmer air and higher humidity or amount of water vapor.

Dust storm affects UAE

The United Arab Emirates experienced a dust storm over the weekend. According to the National Center for Meteorology and Seismology (NCMS), high winds whipped up the dust and sand, leading to road accidents due to the reduced visibility.

Cases of asthma and other respiratory illnesses also increased to 25 percent. Child asthma and Allergy Specialist Dr. Pierre Majdalani said dustry air can trigger cough, cold, ear infection, asthma, viral infection and influenza.

NCMS meteorologist Sufian Farrah explained that a dust storm occurs when wind speed exceeds 30 kilometers per hour with visibility dropping to 1,000 meters or less. Farrah added that dust or sandstorms are normal during this time of the year.
