A major hurricane force storm continues over the western North Pacific with winds up to 65 knots and significant wave heights up to 20 meters (about 66 feet)! The significant wave height is the average of the 1/3 highest waves which means that some waves will be higher. Given a significant wave of 20 meters, about 1 in 10 waves could be 25 meters (82 feet) and 1 out of 100 could be as high as 33 meters (108 feet)!
Previously reported on 15 January:
A very dangerous 936 mb storm peaked today over the western North Pacific with a min pressure of 932 mb and is moving northeast at 25 knots with hurricane force winds and very high sea and swell conditions. Hurricane Sandy, by comparison, reached a minimum pressure of 940 millibars and was the largest Atlantic hurricane in recorded history.
At 12Z 15 January the center of the storm was near 42N/163E with winds of Force 11 or higher (60-85 knots) and waves 12-18 meters (39-59 feet) within 300NM west and southwest of the center and winds forces 9-11 and waves 5.5-14 meters (18-46 feet) up to 540NM from the center.
This storm and will now weaken slowly as it moves northeastward.
Keep in mind that the wave heights here are the significant wave height which is defined as the average of the 1/3 highest waves. This means that some individual waves could be up to twice the significant wave height!
This storm appears to be an example of a rapidly deepening “bomb” low that is often associated with some winter season storms over both the North Atlantic and North Pacific oceans. These systems are associated with what is known as a warm air seclusion where the warm surface air is lifted up during the occlusion process and then wrapped around the low center into its cold southwestern quadrant.
932 millibars!

President Donald Trump indicated that he might be preparing to ease his “maximum pressure” campaign against Iran, potentially undercutting a central policy dating to his first term and provoking consternation among foreign policy hawks who argue that now is the time to escalate — not lessen — pressure on Tehran.
