Typhoon Carina is currently affecting the Philippines, prompting PAGASA and NDRRMC to continue issuing warnings and alerts, but what do these messages mean?
The Philippines experiences two main seasons: the rainy season from June to November, and the dry season from December to May.
During the rainy season, the PAGASA issues warnings called “Tropical Cyclone Wind Signals” for different areas.
These signals aim to warn the public about the strength of the wind and rain brought by a tropical cyclone or typhoon.
There are five levels of wind signals, from Signal #1 to Signal #5.
Signal #1 indicates wind speeds of 39 to 61 kilometers per hour. Light moderate damage can be expected for houses made of lightweight materials.
Signal #2 warns of wind speeds of 62 to 88 kilometers per hour. Structures that are poorly constructed may suffer damage. Many trees and rice crops may be uprooted or broken.
Signal #3 indicates wind speeds of 89 to 117 kilometers per hour. Many read may experience power outages due to damaged power lines and poles. Most trees may fall.
Signal #4 warns of wind speeds of 118 to 184 kilometers per hour. Severe damage is expected to structures, similar to what happened during Super Typhoon Yolanda. It can also cause injuries and possible fatalities.
Finally, Signal #5 indicates wind speed of 185 kilometers per hour or higher, similar to Super Typhoon Egay last year. Extensive damage to risk of injury or death. There will also be long-term power outages, lack of clean water, and telecommunications disruptions. Few trees, plants, and crops will survive.
In addition to Tropical Cyclone Wind Signals, PAGASA also uses color-coded rainfall warning icons. There are three colors: yellow, orange, and red.
The warning starts with yellow, which is an “advisory”. It means moderate rainfall to 7.5 to 15 millimeters per hour is expected.
The community should be aware as flooding is possible in low-lying areas and near rivers.
The orange warning means people should be alert and ready for possible evacuation as heavy rainfall of 15 to 30 millimeters in the next three hours is expected.
This can cause severe flooding, threatening life and property, especially in low-lying areas and near rivers.
For all these warnings, PAGASA advises the public to stay updated with official weather updates and prepare necessary safety measures.
Understanding PAGASA’s warnings can help us stay safe during times of danger.
