VICENTE (FERDIE) is expected to move NW to WNW for the next 24 hours and bend Westward throughout the forecast period. On the forecast track, the core of Vicente will pass about 110 km to the SSW of Hong Kong early Tuesday morning and make landfall over Western Guangdong, just to the WSW of Macau around sunrise Tuesday. By whole day Tuesday until Thursday, the system will cross the rugged terrain of Southern China and Northernmost Vietnam.

Maximum Sustained Winds (1-min. avg) have increased to near 120 km/hr (65 knots) with higher gusts. Additional strengthing is expected within the next 12 hours, before it makes landfall and Vicente (Ferdie) will start to weaken, dissipate as it tracks inland beginning Tuesday morning through Thursday.

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 (62-100 km/hr) extend outward up to 195 kilometers (105 nautical miles). VICENTE is a large-sized tropical cyclone with a diameter of 835 kilometers (450 nautical miles).

The following is the summary of the 3-day forecast outlook on this system:

TUESDAY AFTERNOON: Downgraded to a Tropical Storm (TS) after making landfall over Western Guangdong and traverses the rugged terrain of Southern China...about 137 km NE of Zhanjiang, China [2PM JUL 24: 22.2N 111.4E @ 100kph].
WEDNESDAY AFTERNOON: Downgraded to a Tropical Depression (TD) as it moves rapidly westward across the Chinese-Vietnamese Border and into Northern Vietnam...about 192 km North of Hanoi [2PM JUL 25: 22.7N 106.1E @ 55kph].
THURSDAY AFTERNOON: Dissipates near the Vietnamese-Chinese Border as an area of low pressure...about 267 km WNW of Hanoi [2PM JUL 26: 22.4N 103.7E @ 35kph].


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

CLOUD-FILLED 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).
EYEWALL - over water (South China Sea)...not yet affecting any land areas...but will reach the coastal areas of Western Guangdong later tonight or early Tuesday. Hong Kong and Macau may not be spared if the NNW track continues. Typhoon Conditions with Typhoon Force Winds (>118 kph) will be expected within this wall (click here to know more about the Eyewall).
INNER RAINBANDS - affecting and spreading across Hong Kong, Macau and Western Guangdong (between east of Zhanjiang up to east of Hong Kong). Tropical Storm Conditions with Tropical Storm Force Winds (62-94 kph) will be expected along these bands.
OUTER RAINBANDS - affecting & spreading across Hainan and the rest of Southern China including SW Taiwan. 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 Vicente (Ferdie). (click to open NOAA's eTRaP graphic).
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 Hong Kong, Macau and Western Guangdong. Minimal damage is likely on this type of storm surge. Danger from Rip Currents or Rip Tides can be expected along the rest of the beach-front areas of Southern China, Western Taiwan and Western Luzon (Philippines).

The Tropical Disturbance 93W (LPA) over the Caroline Islands, near Palau Island not yet organized. Various dynamic computer models still continues to show possible development into a Tropical Depression within the next 2 to 3 days. Its center was located about 268 km SSE of Koror, Palau or 1,022 km ESE of Mindanao, Philippines (5.0N 135.5E)...with maximum sustained winds of 30 kph and was moving West @ 22 kph towards the Philippine Sea. The 24-hour TC Formation Potential remains LOW (<30% Chance).

CURRENT SW MONSOON INTENSITY: MODERATE >> Cloudy skies with passing occasional showers, rains or thunderstorms w/ squalls will be expected along the following affected areas: CENTRAL & NORTHERN LUZON incl. METRO MANILA, and MINDORO. Light to moderate SW'ly winds (not in excess of 35 kph) will blow across the abovementioned areas.
