Super Typhoon Haima (Lawin) Reaches Category 5 Strength; Targets Northern Philippines
By Jon Erdman and Chris Dolce, Oct 18 2016 11:26 PM EDT weather.com
Super Typhoon Haima has rapidly intensified to Category 5 strength, and will be the second typhoon in four days to hammer the northern Philippines Wednesday, before turning toward southeast China late this week.
Haima was centered about 345 miles east-northeast of the Philippine capital, Manila, as of midday Wednesday, local time.
Infrared satellite imagery shows a classic, intense, west Pacific super typhoon with a large eye and an intense ring of convection surrounding it. The Japanese Meteorological Agency estimated Haima's central pressure had dipped to 900 millibars, and a satellite estimate from the University of Wisconsin estimated a pressure of 910 millibars Tuesday evening, U.S. time.
The highest cloud tops, corresponding to the most vigorous convection, are shown in the dark red and purple colors.
Maximum sustained winds in Haima increased from 85 mph late Sunday morning to 160 mph by Tuesday morning (U.S. time), which means the typhoon has undergone rapid intensification. Rapid intensification is when maximum sustained winds increase by at least 30 knots (about 35 mph) in 24 hours or less.
The outflow of winds aloft exhausting the top of Haima, low wind shear and warm, deep ocean water set the stage for Haima's rapid intensification.
Steered by high pressure aloft to its north, Haima will make landfall in northern Luzon, Philippines, overnight Wednesday night, local time (the Philippines are 12 hours ahead of U.S. EDT) as a strong, dangerous typhoon.
The area in red indicates the potential path of the center of the tropical cyclone. Impacts such as outer bands of heavy rain and high surf may extend some distance beyond the cone.
Haima, known as "Lawin" in the Philippines, will likely make landfall farther north along the northeast Luzon coast than Sarika/Karen did.
Along with the dangers of storm surge flooding and damaging winds, rainfall flooding and landslides would also be major threats in Luzon, given saturated ground from Sarika/Karen, and the considerable mountainous terrain of northern Luzon. More than a foot of rain is likely to fall over northern portions of Luzon as Haima moves through.

MANILA - "Lawin" (international name "Haima") is now a super typhoon, the U.S. Naval Observatory's Joint Typhoon Warning Center (JTWC) said Tuesday night.
The U.S. weather agency expects Lawin to continue gaining more strength before making landfall over northern Philippines.
