Forecast: "...15 typhoons, 7 to be intense, in 20% below-norm Northwest Pacific season"

From the re/insurance, cat-bond mavens at Artemis, May 8:

With the development of La Nina conditions anticipated during this summer and its persistence through the autumn, Tropical Storm Risk (TSR) has called for the Northwest Pacific typhoon season to see activity levels around 20% below normal, albeit still with 15 typhoons, 7 of which are forecast to be intense.

The expectation that La Nina conditions will develop during summer and persist through autumn is the key driver here, as it was for Tropical Storm Risk’s forecast for a very active Atlantic hurricane season in 2024.

Just as the change from El Nino to La Nina would be expected to make the Atlantic more conducive to hurricane formation, the opposite is the case in the Northwest Pacific basin.

As a result, TSR said that it predicts the Northwest Pacific typhoon season will see below average activity, around 20% below the 1991-2020 climate norm, during the 2024 season....

....MUCH MORE

Because we come at this stuff from the insurance and energy angles we tend to focus on the Atlantic basin and the Gulf of Mexico.
Once in a while however...
These Pacific monsters make a lie of the ocean's name.

They can be truly terrifying. Super Typhoon Tip, in addition to being immense, also had 190 mph winds:

Here's 1979's Super Typhoon Tip:

The relative sizes of the United States, Typhoon Tip and Cyclone Tracy (the largest and smallest Pacific tropical cyclones recorded, respectively)
About half the size of the contiguous United States.

The combination of size and strength can be very destructive.
There are stories of fleets destroyed by these storms that go back centuries. Kublai Khan's attempted invasions of Japan in 1274 and 1281 were probably thwarted by "kamikaze" (divine wind).

In December 1944 U.S. Admiral Halsey tried to beat past Typhoon Cobra and suffered some large losses:

"...three destroyers,  the Spence, Hickox, and Maddox, capsized and sank in the high seas.  Nine other ships were substantially damaged and over 100 aircraft were lost.  790 men were killed in the typhoon, but 93 sailors were rescued from the sea...." More after the jump.**

A lot of energy in those Pacific storms.
