Super Typhoon Dot (also designated Super Typhoon Saling by PAGASA) was the only super typhoon of the Template:Tcseason, with maximum wind speeds of 150 knots (175 mph or 280 km/h) at peak intensity. Dot is also the sixth-most intense tropical cyclone in terms of wind speed to affect Bicol Region, Philippines between 1947 and 2004.[1]
Storm history
A tropical disturbance in a trough was first detected 150 nautical miles (280 kilometres) southeast of Ponape on October 11. Moving west-northwest, the system reached tropical storm intensity on October 13 south of Guam[2] , and was named Dot.
Continuing its track towards the west, it attained typhoon status north of Yap late on October 14. Continuing to move west-northwestward at a nearly-constant 12 knots, it rapidly intensified on October 15, with the minimum sea-level pressure of the storm deepening 66 millibars in 23 hours - a rate of a drop of 2.8 mb/hour[2] (in comparison, Hurricane Wilma of the 2005 Atlantic hurricane season, the most intense Atlantic storm ever recorded, deepened at a rate of 3 mb/hour at one point). This rapid deepening caused problems with the JTWC's intensity forecasts, and by the end of the day Dot had been upgraded to a super typhoon (winds above or equal to 130 knots).
Dot maintained super typhoon strength until just before its first landfall on the Philippines, crossing Luzon without ever losing typhoon intensity. Once back in open water of the South China Sea, Dot reintensified, peaking at 90 knots south-southwest of Hong Kong.
Weakening, Dot scraped the southern Hainan coast before making its final landfall in the former North Vietnam 130 nautical miles (240 km) south of Hanoi. Dot then dissipated over mountains while inland.
Distinguishing characteristics
Dot had several distinguishing characteristics, mainly the small size of the area of intense convection. Also of note was the small radius of maximum winds, and the lack of a low-level monsoon inflow.[2]
Forecasting difficulties
While there were no difficulties in forecasting Dot's track, its sudden intensity increase on October 15 caused problems with the JTWC's intensity forecasting technique, due to the lack of airplane reconnaissance data.
Preparations in the Philippines
Super Typhoon Dot caused all United States military installations in the Philippines to be placed in a Condition of Readiness I[2] and made an evacuation of Clark Air Base and Cubi Point NAS necessary. Ships in Subic Bay were also moved.
Impact
Philippines
In all in the Philippines, Dot left 74 people dead and more than 50,000 homeless, and left behind over $1.3 million (1985 USD) in damage[2]. However, this figure is considerably limited due to Dot's small size.
Hainan Island
Floods were triggered in the wake of Super Typhoon Dot, which also left two dead on the island. More than 2300 houses also collapsed from Dot's winds.[2]
