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.
