Scope of "Tropical Cyclone Track Probability Forecast” Extended to Central Pacific

"Tropical Cyclone Track Probability Forecast" Extended to Central Pacific

Au Yeung Kin-chung

The Observatory will enhance the "Tropical Cyclone Track Probability Forecast“ this year by extending the forecast area eastward, from the current boundary of 140 degrees east longitude to 180 degrees east longitude, to cover the Central Pacific. When a tropical cyclone is named in the extended area, the automatic probability forecast webpage will show the probability of the tropical cyclone track in the coming nine days. The public can refer to this track probability forecast when preparing to travel abroad, to evaluate whether their destinations would be affected by tropical cyclones, and thus be better prepared.
