The Visible Infrared Imaging Radiometer Suite (VIIRS) on Suomi NPP obtained this satellite picture of Noru on September 25, 2022, a few hours after landfall. Clouds are displayed in infrared brightness temperature level information, which is helpful for differentiating cooler cloud structures (purple) from warmer surface areas below (yellow). The coolest temperature levels (white) are usually related to the highest clouds.

Noru weakened as it passed over the mountainous surface of Luzon, but forecasters anticipated it to enhance once again to the equivalent of a classification 3 storm as it passed over warm waters in the South China Sea. The hurricane could make landfall in central Vietnam on September 27 or 28. Hundreds of thousands of people in Vietnam were preparing to evacuate in advance of the storm.

Super Typhoon Noru. September 25, 2022.
After making landfall in the Polillo Islands and Luzon, the storm enhanced again as it headed toward Vietnam.
” Rapid climax” of a tropical cyclone, according to the technical definition, is a storm with winds that increase by at least 35 miles (55 kilometers) per hour in a 24-hour period. The storms winds enormously accelerated from 50 miles (80 kilometers) per hour on September 24 to 155 miles (250 kilometers) per hour the next day.
Noru made landfall in the Philippines in the night on September 25 as the equivalent of a category 4 storm. It first struck the Polillo Islands prior to making a second landfall about 35 miles (55 kilometers) northeast of Manila on the populated island of Luzon. According to report, the storm resulted in a minimum of six deaths, forced tens of countless people to leave their houses, and knocked out power to 2 provinces.
” Rapid climax” of a tropical cyclone, according to the technical meaning, is a storm with winds that increase by at least 35 miles (55 kilometers) per hour in a 24-hour period. The storms winds massively sped up from 50 miles (80 kilometers) per hour on September 24 to 155 miles (250 kilometers) per hour the next day. Noru made landfall in the Philippines in the evening on September 25 as the equivalent of a category 4 storm. Noru deteriorated as it passed over the mountainous terrain of Luzon, however forecasters expected it to reinforce once again to the equivalent of a category 3 storm as it passed over warm waters in the South China Sea.
