OMAIS is the 97th name in the tropical cyclone name list. It was contributed by the United States, and is a Palauan word meaning "wandering around". This name was used in 2004 and 2010.
OMAIS will accelerate to the northeast along the northwestern periphery of the subtropical ridge.

OMAIS's deep convections are dissipating although its core and low-level structure remains intact. The storm has started extratropical transition and should become fully extratropical before t+24.

OMAIS is now crossing the subtropical ridge axis. It is expected to turn NNE then NE along the northwestern periphery of the ridge, accelerating in the process.

OMAIS's convections are getting loose. It is expected to weaken slightly as it transforms into an extratropical cyclone between t+36 and t+48.

OMAIS is the 97th name in the tropical cyclone name list. It was contributed by the United States, and is a Palauan word meaning "wandering around". This name was used in 2004 and 2010.
OMAIS is expected to move NNW over the next 24 hours and round the western edge of the subtropical ridge. After it crosses the ridge axis near t+36, it will accelerate to the NNE or NE.
A dry area with weak divergence west of OMAIS is causing the storm to lose much of its convections in the western semicircle. The storm is also being affected by the lower sea temperatures (26 to 27 degrees) near 30°N. It is now not expected to reach typhoon strength, but the environment should be able to support the storm's current intensity. Extratropical transition should commence near t+48 and be complete by t+72.

OMAIS is expected to turn NNW soon as it reaches the latitude where the subtropical ridge protrudes to the west. The storm should cross the ridge axis near t+48, after which it will start to recurve and accelerate to the NNE.
Convections in OMAIS's western semicircle have improved. OMAIS should be able to reach typhoon strength soon, but sea temperatures will drop at higher latitudes, limiting its development. The storm should start to weaken near t+36 or t+48, and begin extratropical transition near t+72.
OMAIS has picked up some speed towards the north over the past 12 hours and is intensifying gradually. The JTWC has also upgraded OMAIS into a tropical storm and assigned to it the storm number 07W. At 2 pm, OMAIS was centred about 740 km (400 NM) ESE of Iwo Jima.

Ridging southeast of OMAIS has strengthened and the storm is currently moving north with slight gain in longitude. The storm will continue to move north before being deflected to the NNW due to the westward extension of the subtropical ridge at higher latitudes. OMAIS is expected to cross the ridge axis at around t+72 and recurve towards the northeast along the ridge's northwestern side afterwards, accelerating in the process.
OMAIS has become better organized with more symmetric spiraling convections, although they are still lacking in its western semicircle. The storm should be able to intensify gradually in warm seas with decent outflow channels and rather weak vertical wind shear. Sea temperatures will drop beyond t+48 and the storm will start to weaken. Extratropical transition is expected to start near t+96 and be complete by t+120.
The monsoon depression north of Guam has transitioned into a tropical cyclone. The JMA upgraded this system into a tropical storm this afternoon, naming it OMAIS. The JTWC has meanwhile issued a tropical cyclone formation alert. At 2 pm, OMAIS was centred about 850 km (460 NM) SE of Iwo Jima.

OMAIS is situated west of a subtropical ridge, while there is also ridge influence to the west of OMAIS in the seas east of Taiwan. The eastern ridge is expected to strengthen to the southeast of OMAIS, and some numerical models are predicting a temporary motion towards the N to NNE as the storm moves along the northwestern periphery of that extension. As OMAIS reaches higher latitudes, the western edge of the ridge will exert more influence and deflect the storm to the NNW, before turning to N again at later taus the OMAIS crosses the ridge axis. There is substantial uncertainty due to the difficulty in analysing OMAIS's current position.
Being converted from a monsoon depression, OMAIS covers a large area with the strongest winds in its periphery. The storm will need some time to consolidate, during which the rate of intensification could be slow. The environment is generally supportive of tropical cyclone development, and OMAIS is expected to reach typhoon strength by t+72. Beyond t+72, cooler sea temperatures will result in a weakening trend.
