A new typhoon, Chan-Hom, formed near Guam yesterday but is too far away from Taiwan to pose any immediate threat, the Central Weather Bureau reported.
Chan-Hom, the third tropical storm reported in the Pacific area this year, was moving north-northwest at a speed of 12kph last night.
Meteorologists said that Chan-Hom, which has a radius of 200km, is still more than 3,000km away from Taiwan and it will be 10 days before they can tell if the typhoon will hit the nation.
Weathermen are also watching closely a low pressure system east of the Philippines, which they said may become another severe tropical storm.
Last month, tropical storm Kujira was expected to dissipate into a tropical depression near southeast Taiwan.
Kujira was packing surface winds of up to 90kph, down from 100kph at one point, the Central Weather Bureau reported at the time
Kujira was later downgraded to a tropical depression. Tropical depressions have sustained surface winds of 38kph or less.
Some flights at airports on Orchid Island and Green Island stopped operating as Kujira approached Taiwan and the airports shut down completely at one point.
A typhoon has not hit Taiwan in April in 25 years.
The storm had been centered about 180km southeast of Oluanpi, the southernmost tip of the island, and was moving at 7kph in a northwesterly direction, but it eventually fizzled out, causing virtually no damage.
