Category 5 Typhoon Hayian will struck Philippines
Manila: Super Typhoon Haiyan, the equivalent of a Category 5 hurricane, slammed into the Philippines after forcing thousands of people to evacuate.
Haiyan had top winds of almost 315 kilometres per hour when it was about 489 miles (786 km) southeast of Manila, the US Navy's Joint Typhoon Warning Centre said at 3am Manila time. Winds gusted to as high as 378 km/h, the Navy said.
"If it maintains its strength, there has never been a storm this strong making landfall anywhere in the world," said Jeff Masters, founder of Weather Underground in Ann Arbor, Michigan. "This is off the charts."
The storm went ashore at about 5am in Guiuan, eastern Samar, the Philippines Atmospheric, Geophysical and Astronomical Services Administration said.
Five areas on the island of Visayas, which suffered a 7.2-magnitude earthquake less than a month ago, had been placed on highest storm alert, forecaster Jori Loiz said in a televised briefing. President Benigno Aquino, in a televised address, warned of serious danger and said Haiyan may cause more damage than storm Bopha, which killed more than 1000 people in Mindanao in December 2012.
The Philippines, battered by about 20 cyclones a year, was the nation most affected by natural disasters in 2012, with more than 2000 people killed, according to the Brussels-based Centre for Research on the Epidemiology of Disasters. Monsoon rains swamped more than half of the Manila region in August, causing at least 27 deaths and shutting offices and financial markets for two days.
Haiyan may inundate rivers, create mudflows and cause storm surges as high as 6 meters, Mr Aquino said. Three air force cargo planes, 2 navy ships, helicopters and relief boats are on standby, the president said. About 78,000 families were evacuated in Albay province, Governor Joey Salceda said on his Facebook account.
Mr Masters said Tacloban, the capital of the Philippine province of Leyte, would take a direct hit and winds of at least 209 km/h may sweep as far as 160 km/h inland.
"There isn't much built on the Philippines that can withstand winds like that," Mr Masters said.
Heavy rains from storms usually cause the highest death tolls on the Philippines, Masters said. Flooding may not be the worst threat this time because Haiyan is moving fairly fast. The high winds and storm surge have the potential to cause catastrophic damage, he said.
The true power of Haiyan isn't known because reconnaissance planes haven't flown into it, Mr Masters said. The strongest tropical cyclone on record was Super Typhoon Nancy in 1961 with top winds of 346 km/h. He said many believe the estimated wind speeds of storms between the 1940s to 1960s was too high.
Since 1969, only three storms have been as powerful as Haiyan, Mr Masters wrote on his blog: Super Typhoon Tip in 1979 in the Pacific and Atlantic hurricanes Camille in 1969 and Allen in 1980.
The strongest storm to hit land was Camille, which went ashore in Mississippi with winds near 313 km/h, Mr Masters said. While there are some estimates that Camille's winds were closer to 321 km/h, the exact speed is unknown because the instruments were destroyed, according to the US National Hurricane Center.
The Philippines government has placed relief supplies worth 195 million pesos ($US4.5 million) in Samar and Leyte islands in the Visayas, Communications Secretary Sonny Coloma said in Manila.
After crossing the Philippines, Haiyan is expected to strike Vietnam in several days, according to the Japanese Meteorological Agency.
"It is going to be a huge problem for Vietnam and Laos," Mr Masters said. As much as a foot of rain may fall there, he said.
SUPER TYPHOON 31W (HAIYAN), LOCATED APPROXIMATELY 425 NM SOUTHEAST OF

SIX HOURS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 071800Z IS 50 FEET.
