Typhoon Force Winds (118 km/hr or more) extend outward up to 30 kilometers (15 nautical miles) from the center...and Tropical Storm Force Winds (62-117 km/hr) extend outward up to 165 kilometers (90 nautical miles). PAKHAR (02W) is an average-sized tropical cyclone with a diameter of 445 kilometers (240 nautical miles).

Below is the summary of the storm's parts and its hazards affecting specific areas:

DEVELOPING EYE - over water (South China Sea). Possible calm and lull conditions (with <20 kph winds) will be expected inside the eye (click here to know more about the EYE).
DEVELOPING EYEWALL - over water (South China Sea). Typhoon Conditions with Typhoon Force Winds (>118 kph) will be expected within this wall (click here to know more about the Eyewall).
INNER RAINBANDS - over water (South China Sea)...not yet affecting land areas. Tropical Storm Conditions w/ Strong Winds (62-117 kph) will be expected along these bands.
OUTER RAINBANDS - affecting & spreading across Southeastern & Southern Vietnam & some portion of Spratly Islands. Cloudy/Rainy Conditions w/ moderate to strong winds (<62 kph) will be expected along these bands (click here to know more about Rainbands).
24HR TOTAL RAINFALL ACCUMULATION - from 5 up to 200 mm (low to high rainfall) can be expected along areas affected by the outer & inner rainbands (see above)...with isolated amounts of 201 to 500 mm (high to very high) along areas near the center of PAKHAR (02W).

COASTAL STORM SURGE FLOODING - possible 4-5 ft [1.2-1.7 m] above normal tide levels...accompanied by large and dangerous battering waves can be expected along the coastal, inland lakes and beach front areas of Southern & SE Vietnam beginning Saturday until its projected landfall on Sunday.
