How to read and understand our storm information?
| Name (INTL. / local): | The international community and the Philippines give always two different names to a cyclone. The international name is in CAPITAL LETTERS, the Pinoy name is in normal Writing. |
| Class: | Cyclones are classified by their wind speed. The classification is also known as the Saffir-Simpson scale. |
| Time/Date of observation: | We always indicate date and time of the observation. Sometimes cyclones can change their behavior quickly. |
| Location of Center: | The geographical coordinates of the cyclone’s center at observation time. |
| Moving Direction and Speed: | Predicted moving direction N=North, E=East, S=South, W=West. WNW means West to North-West. We also indicate the transition speed of the cyclone’s center. this is not the wind-speed. |
| Moving towards: | Direction towards which the cyclone’s center moves. Usually we indicate an island or a region. |
| Distance from the Philippines: | Nearest distance of the cyclone’s center from the Philippines. |
| Estimated Date / Time of Landfall: | If the cyclone could make landfall, we try to estimate where and when it will hit an island. |
| Max. Wind Speed near Center: | This is the maximum circular wind speed around the centre of the cyclone. We indicate it in kilometers per hour and miles per hour. |
| Peak Wind Gusts: | This is the maximum of gusts within the cyclone. We indicate it in kilometers per hour and miles per hour. |
| Minimum Central Pressure: | This is the atmospheric pressure in the center of the cyclone. At a pressure 1010 hPa of you can expect fair weather. At around 1000 hPa it gets windy. Below you have to expect a storm. Severe typhoons go down to a pressure of 920 hPa. hPa is the international unit for pressure. It means hecto-Pascal. |
| Diameter: | This is the width of the wind system from one edge to the other. We indicate it in kilometers and statute miles. |
| 24h Rainfall near Center: | This is the height of the accumulated rainfall in 25 hours near the center. We indicate it in millimeters and inches. |
| Max. Wave Height: | This is the maximum wave height of the sea near the center. We indicate the height in meters and feet. |
