THE Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa)-Mactan station has recorded a total of 34 millimeters (mm) of rain from 8 a.m. of Tuesday, September 15, to 8 a.m. of Wednesday, September 16, 2020.
Netherlen Delfin, weather specialist at Pagasa-Mactan Station, said this is equivalent to a total of 170,000 drums or barrels of rainfall that fall in an area of one square kilometer.
Every one mm of rain is equivalent to 5,000 drums or barrels of rain per square kilometer.
She said the rain was particularly concentrated between 8 p.m. of Tuesday until 2 a.m. of Wednesday.
"Dili ra siya katupong sa average rainfall nato in a month. However, from September 1 to September 15 nga rainfall, nakaabot na ta sa 40 percent of expected rainfall for the month," she said.
She said the rain was the direct effect of southwest monsoon or "habagat," which is the prevailing weather system in the entire Visayas.
She said the Tropical Storm Leon, though far from the Visayas area, has indirectly intensified and enhanced the habagat.
Pagasa-Mactan issued an orange warning level in Central Cebu and the rest of Palawan, Occidental Mindoro, Southern Leyte, and Negros Occidental at 11:10 a.m. Wednesday.
This means flooding is threatening in low-lying areas, and landslide in mountainous areas is possible.
It also raised yellow warning level in Leyte, Bohol, and Negros Oriental, which also means the possibility of flooding and landslides.
The public and the disaster risk reduction and management council concerned are advised to take appropriate actions and the weather condition. (WBS)
