Tropical Storm Chaba rapidly gaining more strength as it moves toward the Okinawa area

Tropical Storm Chaba (Katring/16W)

As of 12 p.m. PST, October 25, 2010

• 17.2N 130.6E
• 1092.68 km. South-Southeast of Kadena AB, Okinawa, Japan
• currently moving northwestward @ 11 kph
• maximum sustained winds: 83 kph
• gustiness winds: 102 kph
• minimum sea level pressure: 992 MB
• maximum sea wave height: 17 feet
• heading towards Okinawa, Japan area
• Saffir-Simpson Typhoon Scale: Tropical Storm

Latest satellite imagery depicts that Tropical Storm Chaba  has improved it's deep convection banding for the past 6 hours along the southern and western periphery of the low level circulation center (LLCC). Numerical weather guidance models support the intensification of this system within the next 2-3 days. On October 26. it shall anticipated to move NW-Northward @ 24 kph as a Typhoon (Category 1) with a maximum sustained winds of 130 kph. It shall resume it's  N-NNE track as it moves toward the Okinawa, Japan area on Thursday as a Typhoon (Category 2) with a maximum sustained winds of 158 kph/167 kph. It shall continue tracking it's NE direction as Category 1 system after passing Okinawa area late Saturday morning.

Precautionary measures must be properly implemented along the projected area.

Tropical Depression barely moving Southwest @ 09 kph towards the Central Philippine Sea

Tropical Depression 16W (Katring) 

 As of 6 a.m. PST, October 24, 2010

• 15.4N 132.8E
• 1333.44 km. South-Southeast of Okinawa, Japan
• currently moving westward @ 09 kph
• maximum sustained winds: 56 kph
• gustiness winds: 74 kph
• minimum sea level pressure: 1004 MB
• maximum sea wave height: 13 feet
• heading towards Philippine Sea
• Saffir-Simpson Typhoon Scale: Tropical Depression

Tropical Depression 16W continues to consolidate more strength as more numerical guidance models support the possible intensification of Tropical Depression 16W  in to a Tropical Storm within the next 12 hours (maximum sustained winds: 65 kph). It is anticipated to resume it's track beginning tomorrow in NW-WNW direction as a Tropical Storm and forecasts to accelerate on Tuesday at the speed of 24 kph with the possible sustained winds of  74 kph/93 kph/111 kph as it moves toward N-NNE heading Okinawa area on Thursday.

Typhoon Megi now on it's second lanfall towards Southeastern China..TD 16W on it's way to Philippine Sea..TD 17W trying to survives

Typhoon Megi (Juan/15W)

 As of 7 a.m. PST, October 23, 2010

• 23.7N 118.1E
  
• 425.96 km. East-Northeast of Hong Kong
• currently moving northward @ 11 kph
• maximum sustained winds: 130 kph
  
• gustiness winds: 85 kph
  
• minimum sea level pressure: 970 MB
  
• maximum sea wave height: 21 feet
  
• heading towards Southeastern China
  
• Saffir-Simpson Typhoon Scale: Category 1

Typhoon Megi slowly decreasing it's strength as it is forecasts to make it's second landfall this afternoon. The main reason of weakening of this system is that it is tracking under the influence of moderate vertical wind shear and increased subsidence. Based on the latest satellite imagery , the central convection has shallowed and contracted towards the center and the large eye is completely cloud filled. Typhoon Megi is expected to dissipate within 12-18 hours once this sytem will make it's second landfall today.

Precautionary measures must be properly implemented along the affected area while Western Taiwan and Southeastern China are alerted against storm surge.

Tropical Depression 17W

Latest weather update will be issue around 8-10 a.m. PST, October 23, 2010

Typhoon Megi now heading towards Southeastern China..Tropical Depression 16W gains more strength while 17W now a Tropical Depression

Typhoon Megi (Juan/15W)

• 20.7N 118.0E
• 435.22 km. East-Southeast of Hong Kong
• currently moving north-northeastward @ 7 kph
• maximum sustained winds: 167 kph
  
• gustiness winds: 204 kph
  
• minimum sea level pressure: 945 MB
  
• maximum sea wave height: 34 feet
  
• heading towards Southeastern China
  
• Saffir-Simpson Typhoon Scale: Category 2

Typhoon Megi is expected to decrease it's strength as it becomes as a Category 1 within the next 12 hours with a maximum sustained winds of 130 kph. It is anticipated to move faster at 24 kph as it approaches the coast of Southeastern China beginning early tomorrow morning o it's second landfall as a Tropical Storm with the maximum sustained winds of 102 kph. It shall continue to move over the Zhangzhou Province where complete dissipation process is possible on Sunday.

Tropical Depression 16W

• 17.3N 139.4E
• 842.66 km. South of Iwo To, Japan
• currently moving westward @ 19 kph
• maximum sustained winds: 46 kph
  
• gustiness winds: 65 kph
  
• minimum sea level pressure: 1002 MB
  
• maximum sea wave height: 10 feet
  
• heading towards Philippine Sea
  
• Saffir-Simpson Typhoon Scale: Tropical Depression

Tropical Depression 16W has consolidated strength for the past 6 hours as it moves toward westward. Latest satellite imagery depicts that Tropical Depression 16W is moving under the steering influence of the low-level subtropical ridged found to the north of the system. That is why, Tropical Depression 16W is expected to move westward within the next 72 hours and resume it's main track towards WNW on October 25.

PAGASA also reported that this system might enter the Philippine Area of Responsibility (PAR) on Saturday. Global numerical weather agency's such as ECMWF forecasts to move in W-WNW direction and did not run this system to affect the country but instead towards Okinawa, Japan area.

Tropical Depression 17W

• 21.0N 155.7E
• 1,444.56 km. Northeast of Hagatna, Guam
• currently moving west-northwestward @ 17 kph
• maximum sustained winds: 56 kph
  
• gustiness winds: 74 kph
  
• minimum sea level pressure: 1006 MB
  
• maximum sea wave height: 10 feet
  
• Saffir-Simpson Typhoon Scale: Tropical Depression

Tropical Depression 17W is expected to move in WNW direction and forecasts not to intensify signicantly within the next 24-48 hours. Unfavorable environmental factors such as upper level divergence, easterly vertical wind shear and the drier air that that moves toward in the center coming from the southeast region prevents the possible intensification. Complete dissipation process is possible within the next 48 hours.

Typhoon Megi weaken it's strength as it moves toward Southeastern China..95W now a Tropical Depression...while 98W consolidates more strength

Typhoon Megi has gradually weaken it's strength over the past 6 hours however the latest IR imagery depicts an intense system with a banding eye and most of the convective band is found over the northwestern quadrant located over the South China Sea. Typhoon Megi is expected to decreasing it's strength as it moves to unfavorable environment and forecasts to move North-Northeastward direction in the 24-36 hours and resume it's track on October 22 as a Category 1 system (139 kph) as it approaches the coast of Southeastern China near Zhangzhou Province.

Proper precautionary measures must be implemented along the affected area. Strong storm surge is possible along the Northwestern seaboard coast of Luzon, Batanes and Western Taiwan is expected to prevail starting today as it moves to North-Northeastward direction.
