EFFECTS & HAZARDS SUMMARY
Below is the summary of the storm\'s parts and its hazards affecting specific areas:
CENTRAL DENSE OVERCAST (CDO) - over water (South China Sea)...not yet affecting any land areas...possible \"Eye\" forming underneath the cirrus canopy. Near-Typhoon Conditions w/ Near-Typhoon Force Winds (95-117 kph) will be expected along the CDO.
INNER RAINBANDS - over water (South China Sea)...not yet affecting any land areas...will reach the coastal areas of Western Guangdong & Eastern Hainan late Monday or early Tuesday. Tropical Storm Conditions with Tropical Storm Force Winds (62-94 kph) will be expected along these bands.
OUTER RAINBANDS - affecting & spreading across Hainan and Southern China particularly Guangdong Province. Cloudy/Rainy Conditions w/ moderate to strong winds (<62 kph) will be expected along these bands.
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 400 mm (high to very high) along areas near the center of Vicente (Ferdie).
COASTAL STORM SURGE FLOODING - possible 1-3 ft (0.3-0.9 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 Hainan Island and Southern China. Very 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 Vietnam and Western Luzon (Philippines).
TROPICAL CYCLONE WATCH
A new and developing Tropical Disturbance 93W (LPA) has been detected over the Caroline Islands, near Palau Island.
