Typhoon force winds has been felt across Hong Kong, Macau and parts of Western Guangdong. The weakening eye of the typhoon is now in the vicinity of Taishan, China.

VICENTE will continue to enhance the Southwest Monsoon (aka. Habagat) across Northern and Central Luzon particularly the western sections. Breezy conditions & mostly cloudy conditions w/ occasional to sometimes continuous rains, thunderstorms & squalls will be expected along the abovementioned areas today.

Residents and visitors along Southern China particularly Guangdong Province should closely monitor the progress of Vicente (Ferdie).

VICENTE (FERDIE) is expected to move WNW for the next 12 to 24 hours and bend Westward throughout the forecast period. On the forecast track, the core of Vicente will traverse Southern China through Western Guangdong and Guangxi Provinces beginning today until Wednesday afternoon. By Wednesday evening through Thursday morning, VICENTE will be moving parallel along the Chinese-Vietnamese Border.

Maximum Sustained Winds (1-min. avg) are near 215 km/hr (115 knots) with higher gusts. Rapid weakening is expected within the next 24 hours as Vicente (Ferdie) moves across land (Southwestern China). Complete dissipation is forecast on Wednesday evening or early Thursday.

Typhoon Force Winds (118 km/hr or more) extend outward up to 65 kilometers (35 nautical miles) from the center...and Tropical Storm Force Winds (62-100 km/hr) extend outward up to 205 kilometers (110 nautical miles). VICENTE is a large/average-sized tropical cyclone with a diameter of 665 kilometers (360 nautical miles).

The following is the summary of the 2-day forecast outlook on this system:

WEDNESDAY EARLY MORNING: Downgraded to a Tropical Storm (TS) as it traverses the rugged terrain of Southern China...or over Guangxi Province [2AM JUL 25: 22.9N 108.3E @ 110kph].
THURSDAY EARLY MORNING: Dissipates along the Chinese-Vietnamese Border...just an area of low pressure [2AM JUL 26: 22.9N 103.8E @ 35kph].


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

WEAKENING EYE - over Taishan, China. Possible calm and lull conditions (with <20 kph winds) will be expected inside the eye (click here to know more about the EYE).
EYEWALL - affecting parts of Western Guangdong particularly Taishan-Chixizhen, China. 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. 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 350 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 13-18 ft [4-5.5 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. Extreme 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 has entered the Philippine Area of Responsibility (PAR) but remains weak and disorganized. Various dynamic computer models still continues to show possible development into a Tropical Depression within the next 3 to 4 days. Its center was located about 324 km SSW of Koror, Palau or 814 km SE of Mindanao, Philippines (4.5N 133.4E)...with maximum sustained winds of 30 kph and was moving NW @ 15 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 particularly the western sections. Light to moderate SW'ly winds (not in excess of 35 kph) will blow across the abovementioned areas.

Important Note: Please keep in mind that the above forecast outlook, effects-hazards, current monsoon intensity, & tropical cyclone watch changes every 6 to 12 hrs!
