Tropical storm Feria almost slammed the towns of San Pascual, Bauan and other barangays in Batangas City yesterday. Though storm signal no. 1 was hoisted over the province, the aforesaid areas experienced tornado and hailstorm.
On the other hand, a lot of local folks are wondering why such phenomenon (hailstorm) occur. To better understand the existence of these hailstones or hailstorm, here’s what we have researched: Hailstones are usually consist mostly of water ice and measure between 5 and 150 millimeters in diameter, with the larger stones coming from severe and dangerous thunderstorms. It sometimes, though not always, occurs during a tornado warning but not as a result of a tornado itself. Hail can occur within any thunderstorm. Hail is only produced by cumulonimbi (thunderclouds), usually at the front of the storm system, and is composed of transparent ice or alternating layers of transparent and translucent ice at least 1 mm thick.
Hail forms in storm clouds when supercooled water droplets freeze on contact with condensation nuclei, such as dust or dirt. The storm’s updraft blows the hailstones to the upper part of the cloud. The updraft dissipates and the hailstones fall down, back into the updraft, and are lifted up again. The hailstone gains an ice layer and grows increasingly larger with each ascent. Once a hailstone becomes too heavy to be supported by the storm’s updraft, it falls from the cloud.
Meanwhile, it was reported today that Bauan Batangas is now on a state of calamity. Feria continues to hit the town, uprooting trees and causing mudslide and floods in Bauan areas.
With this, the Provincial Disaster Coordinating Council (PDCC) advised the public specially those residing on coastal areas to evacuate their houses. It is forecasted that tropical storm Feria will hit Batangas area at 8:00 pm tonight and people’s safety is of course PDCC’s priority.
