Well, We've got some Big Time Weather going on in the Pacific.

Typhoon Bopha is threatening a Dead Center hit on the Phillipines.  Projected CAT 5 Strength with sustained winds of up to 160 mph.

This may all be a factor of Climate Change

Outside influences such as NEXRAD

Upcoming and current Stellar Alignment is affecting Weather Patterns to the Extreme

Category 5 Super Typhoon Bopha bearing down on the Philippines - http://www.wunderground.com/blog/JeffMasters/article.html?entrynum=2303

Published: 3:41 PM GMT on December 03, 2012
Extremely dangerous Typhoon Bopha is bearing down on the Philippine island of Mindanao as a Category 5 storm with 160 mph winds. Bopha completed an eyewall replacement cycle on Sunday and has been steadily intensifying today, and will make landfall on Mindanao in the early morning on Tuesday local time. Mindanao rarely gets hit by typhoons, since the island is too close to the Equator, and the infrastructure of Mindanao is not prepared to handle heavy typhoon rains as well as the more typhoon-prone northern islands. Bopha is potentially a catastrophic storm for Mindanao. The typhoon is following a similar track to last year's Tropical Storm Washi, which hit Mindanao on December 16, 2011 with 60 mph winds and torrential rains. Washi triggered devastating flooding that killed 1268 people. Washi was merely a tropical storm, and Bopha is likely to hit at Category 4 or 5 strength, making it the strongest typhoon ever recorded in Mindanao.

Bopha: the most southerly typhoon on record
Bopha became a tropical depression unusually close to the Equator, at 3.6°N latitude. Tropical cyclones rarely form so close to the Equator, because they cannot leverage the Earth's rotation to get themselves spinning. According to hurricane expert Dr. Paul Roundy of SUNY Albany, Bopha got its spin from a large-scale atmospheric wave called a mixed Rossby gravity wave. Because of the lack of atmospheric spin so close to the Equator, it took Bopha over four days to intensify into a typhoon, and it stayed a relatively small storm. Bopha became the most southerly typhoon ever recorded in the Western Pacific at 06 GMT on November 30, when the storm was at 3.8°N latitude. The previous most southerly typhoon was Typhoon Kate of 14 - 25 October 1970, which reached typhoon intensity at 4.3°N, 137.4°E. Bopha continued intensifying over the weekend, becoming the second most southerly super typhoon ever recorded (150 mph winds) at 00 GMT on December 1, when it was at 6.1°N latitude. The record most southerly super typhoon was Kate, which reached super typhoon intensity at 6.0°N, 126.3°E. Kate struck the Philippine island of Mindanao as a Category 4 storm, killing 631 people. Bopha further intensified into a Category 5 typhoon on Monday at 7.4°N latitude, becoming the second most southerly Category 5 typhoon on record, next to Typhoon Louise of 1964, which was a Category 5 storm at 7.3°N. According to NOAA's Coastal Services Center, there have been only 4 previous typhoons of at least Category 4 strength to track within 200 nautical miles of Mindanao Island, dating back to 1945: Mike ("Ruping" ) in 1990, Ike ("Nitang") in 1984, Kate ("Titang") in 1970, and Louise ("Ining" ) in 1964.

The closest a tropical cyclone has ever been to the Equator is 0.7°N, by Tropical Cyclone Agni in the North Indian Ocean in November 2004. Agni got counter-clockwise spin from the presence of the summer monsoon circulation in the Indian Ocean. The closest a Western Pacific tropical cyclone has been to the Equator is 1.4°N latitude, by Tropical Storm Vamei on December 27, 2001. Vamei hit Singapore after Christmas in 2001, at a latitude of 1.5°N.

Mindanao bracing for 260 to 315 kph winds from Super Typhoon 'Pablo' - http://www.voxbikol.com/article/mindanao-bracing-260-315-kph-winds-super-typhoon-pablo



Naga City (1:00 AM Dec 4, 2012) - Super typhoon 'Pablo' (International Name: Bopha) has intensified further few hours before its expected landing somewhere in Surigao del Sur or Davao Oriental.
At midnight today (one hour ago), its center was spotted 173 km East Southeast of Bislig City in Surigao del Sur.

Typhoon expert David Michael V. Padua of Weather.com.ph projects that Pablo shall be an 'extremely catastrophic Category 5 Supertyphoon' when it hits land somewhere along Cateel Bay, Davao Oriental at 4-6 AM today as it packs a sustained center wind of 260 km/hour and gusts up to 315 kph .
Pablo is almost 3 times the strength of Sendong that crossed North-Central Mindanao on December 16, 2011 wiping out entire villages and leaving 1200 dead.
This Super Tyhoon can become the most devastating typhoon ever to hit Mindanao since Super Typhoon Kate (Titang) in October 1970.

The government and private entities have braced for Pablo over the past several days with the best preparation and disaster preparedness plans it can muster. Rainfall caused by Pablo is classified as Extreme at 400 mm over 24 hours.

On the forecast track, the core of Bopha is expected to make landfall along the Davao Oriental-Surigao Del Sur Border this morning (approx. 4-6 am Manila Time)...and cross Surigao Del Sur, Agusan Del Sur and Misamis Oriental Tuesday morning until the early afternoon, passing over or very close to Cagayan De Oro City between 1-2 pm. By Tuesday evening, Bopha should emerge over the Bohol Sea near the coast of Misamis Occidental, and then traverse Southern Coast of Negros passing just south of Dumaguete City between 6 to 8 pm. This typhoon will then traverse Sulu Sea Wednesday morning...and pass along the northern tip of Palawan, very close to El Nido, Palawan by Wednesday evening.
