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.|
