During Sunday, this storm has intensified rapidly and given that winds have reached 60 knots at the centre, this storm has effectively reached the thresh hold of a typhoon. It is now encroaching the Mariana Islands and Guam. The plot acquired from CIMSS suggests the core passing over or near the Mariana Islands.
The attached image acquired from NASA 2 August (MODIS) also shows the storm in great detail including the nearby islands super imposed to show their size relative to the storm. Substantial convection (Cumulonimbus cloud towers) are a feature across the storm. A formal eye has not formed but should soon.
Forecast models do suggest a powerful storm (Category 4) in coming days as it takes a north west path towards Taiwan and or China. At the present time, the storm does not threaten a population centre but this could change as the storm continues its north west path across open waters.
