The storm forecast bulletin of the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said that at 7:00 a.m. on September 30, the center of storm Julian was at about 19.9 degrees north latitude, 122.2 degrees east longitude, in the coastal waters of Balintang, Calayan, Cagayan.
The strongest wind near the storm center is 175 km/h (level 15), gusting up to 215 km/h (level 17, super typhoon level) and the central pressure is 940 hPa.
Over the next 24 hours, the storm is expected to move west-northwest at 10 km/h. Strong winds extend out to 560 km from the center of the storm.
PAGASA has issued Storm Wind Signal No. 4 (the highest level), warning of winds of 118 to 184 km/h, posing a serious threat to life and property north of Babuyan and Calayan Islands.
Storm Signal No. 3 (89 to 117 km/h) was also issued for the rest of the Babuyan Islands and the northeastern part of mainland Cagayan (Santa Ana).
During the next 24 hours, very rough seas are expected with waves up to 14 meters high on the Batanes coast; 10 meters on the Babuyan Islands coast; 6 meters on the northern coast of Ilocos Norte; 5 meters on the northern coast of mainland Cagayan and the remaining coast of Ilocos Norte; up to 4 meters on the remaining coast of Cagayan and the Ilocos Sur coast.
PAGASA said Julian could strengthen into a super typhoon on October 1.
Julian will then turn mainly northeast toward Taiwan (China) on October 2 and begin to weaken due to rough terrain there.
Taiwan issued a land warning on September 30 ahead of Typhoon Krathon making landfall on the island's populous west coast, bringing torrential rain and strong winds.
Taiwan (China) is regularly hit by typhoons, but they usually hit along its mountainous and sparsely populated east coast facing the Pacific Ocean.
The Taiwan Meteorological Administration (CWA) forecasts that Typhoon Krathon is expected to make landfall in the port city of Kaohsiung early on October 2, then move across the lower tip of Taiwan (China) and out into the Pacific Ocean.
The storm is expected to strengthen further into a super typhoon with winds of more than 220 km/h, according to Tropical Storm Risk. "The impact is getting bigger and bigger," said Gene Huang, a weather forecaster at CWA, pointing to threats to southwestern Taiwan, adding that it is "rare" for a storm of this strength to directly hit the island's western plains.
Taiwan's government said more than 1,000 rubber boats and 2,200 soldiers were on standby across the island, including the east coast, where up to 1,300mm of rain is expected in the coming days.
Ferry trips to outlying islands were cancelled and some domestic flights were disrupted.
In July, Typhoon Gaemi killed at least 11 people in Taiwan (China).
