After undergoing extremely rapid intensification, Super Typhoon Noru
slammed into the Philippines on September 25, 2022. The storm first
struck the Polillo Islands carrying maximum sustained winds of about
130 mph (209 km/h), or the equivalent of a Category 4 hurricane on the
Saffir-Simpson Hurricane Wind Scale. Noru then made a second landfall
about 55 kilometers (35 miles) northeast of Manila on the populous
island of Luzon.

According to ReliefWeb, Super Typhoon Noru (locally called Karding) was
the strongest typhoon to hit the Philippines this year. At least six
people have died—five of which were emergency responders. The storm
also knocked out power to two provinces and forced the evacuation of at
least 75,000 people.

The storm showed stunning rapid intensification on September 24, with
maximum sustained winds leaping from 85 mph (137 km/h) to 155 mph (249
km/h) in only six hours. That is the equivalent of an Atlantic
hurricane strengthening from a minor Category 1 storm to a strong
Category 5 storm. Meteorologists have only recorded a handful of storms
that have ever intensified so much so quickly. The technical definition
of “rapid intensification” of a tropical cyclone is a storm with winds
that increase by at least 55 kilometers (35 miles) per hour in a
24-hour period.

On September 26, the Moderate Resolution Imaging Spectroradiometer
(MODIS) on board NASA’s Terra satellite acquired a true-color image of
Super Typhoon Noru spinning over the South China Sea after crossing the
island of Luzon, Philippines. Near that time, maximum sustained winds
had dropped to about 90 mph (145 km/h), which is the equivalent of a
Category 1 storm.

At 11:00 p.m. EDT on September 26 (0300 UTC on September 27), the Joint
Typhoon Warning Center advised that Typhoon Noru was located about 590
miles (950 km) west of Manila, Philippines and was tracking westward at
19.5 mph (31 km/h). The storm was rapidly intensifying a second time,
with winds estimated at 144 mph (232 km/h), which is Category 4
strength.

Over the next 24 hours, Noru will be encountering increasing vertical
wind shear, which should cause the winds to drop somewhat before making
landfall in central Vietnam on September 27-28.
