HIGOS is the 69th name in the tropical cyclone name list. It was contributed by the USA, and is the Chamorro word for the fruit fig. This name was used in 2002 and 2008; the latter necessitated a #1 Standby Signal.

HIGOS was relocated as its low-level circulation centre drifted away from the convective mass. It is expected to move north in the next 24 hours along the western periphery of the subtropical ridge.
Under the influence of strong vertical wind shear, HIGOS' upper-level convections were sheared away from the low-level circulation centre, leaving the latter completely exposed. Sea temperatures in that region is also sub-optimal. Without an efficient ventilation mechanism, HIGOS will continue to weaken rapidly, and is expected to dissipate over water by t+24.

HIGOS has picked up some speed. It will move NW in the next 12 hours along the southwestern periphery of the subtropical ridge. As it crosses the ridge axis, HIGOS will turn north and recurve before it reaches 20°N.
HIGOS intensified significantly in the past 6 hours as an eye emerged from within the central dense overcast. This is probably the result of an improved outflow channel. With this intensity, HIGOS becomes the strongest February typhoon in the northwestern Pacific since at least 1970. HIGOS is expected to reach its peak at t+12, after which higher shear and lower sea temperatures will start to weaken the storm.
HIGOS has intensified into a typhoon. At 2 pm, HIGOS was centred about 740 km (400 NM) NE of Chuuk.

Naming 氣旋命名
HIGOS is the 69th name in the tropical cyclone name list. It was contributed by the USA, and is the Chamorro word for the fruit fig. This name was used in 2002 and 2008; the latter necessitated a #1 Standby Signal.
HIGOS is still situated within a pressure col and has been moving W slowly in the past 24 hours. The storm is expected to travel increasingly poleward along the western periphery of the subtropical ridge to the east. Numerical models are converging to a recurving scenario, and our forecast has been adjusted accordingly.
HIGOS' core continued to consolidate over the past 24 hours. Some intensification is expected in the next 24 hours as conditions remain favourable, but the storm will encounter higher shear and lower sea temperatures at higher latitudes, and is expected to weaken quite rapidly beyond t+48.

The subtropical ridge is covering areas both east and west of HIGOS. The eastern ridge has been dominant, causing HIGOS to move N. As the shape of the ridge changes, HIGOS is expected to turn WNW or NW in the next 48 hours. The storm is expected to resume a more northerly track later as the ridge weakens.
Shear near HIGOS eased somewhat and allowed the storm to intensify. Some intensification is expected in the next 24 hours as conditions remain favourable, but strong shear will dominate again later in the forecast period, resulting in HIGOS' weakening.
Tropical disturbance 94W over northwestern Pacific has intensified into tropical depression 02W. At 2 pm, 02W was centred about 720 km (390 NM) ENE of Chuuk.
02W is situated south of a subtropical ridge, and is expected to move W/WNW in the next 48 hours. The ridge may weaken beyond t+48, leading to a more poleward track.
02W is showing decent spiraling bands and an ASCAT scan this morning revealed a well-defined low-level circulation centre. Sea temperatures are warm in that region, but the vertical wind shear is rather high. 02W is expected to intensify slowly in this environment.
