For people living across Guam and the Northern Mariana Islands, early July was another reminder of how quickly conditions can change in the western Pacific. Super Typhoon Bavi arrived as an unusually powerful storm that moved near the islands, bringing damaging winds, heavy rains and dangerous coastal flooding.. According to NASA, The cyclone reached its maximum intensity as it passed through the region, becoming the third Category 5 tropical cyclone in 2026.Satellite images taken at night provide a stunning view of the storm from space. However, the weather systems behind these images are causing real damage on the ground, damaging infrastructure and adding to the recovery challenges posed by a major typhoon just a few months ago.
NASA’s VIIRS instrument reveals stunning view of Super Typhoon Bavi
One of the most unusual sightings of Bawi came from a NASA-supported satellite observation shortly after midnight local time on July 6. The image shows the eye of the storm surrounded by a tightly organized eyewall, with parts of the cyclone illuminated by moonlight from above.The image was collected by the Visible Infrared Imaging Radiometer Suite (VIIRS) aboard the NOAA-20 satellite, according to NASA. At that time, Bawi’s intensity was near its peak. A few hours later, the sight moved to Rota Island, one of the Northern Mariana Islands.Satellite images highlighted how compact and clear the storm became as it moved westward through unusually warm waters.
How El Niño fueled the rapid intensification of Super Typhoon Bavi
Bahrain intensified in areas where sea surface temperatures were around 30 degrees Celsius. Warm water acts as fuel for tropical cyclones, providing the energy needed to strengthen thunderstorms around the storm center.According to NASA, the typhoon reached super typhoon level on July 4, local time, as it moved westward across the Pacific Ocean. As it approached Guam and the Northern Mariana Islands, sustained wind speeds had increased to about 290 kilometers per hour.Meteorologists have been paying close attention to the 2026 Pacific season due to the development of El Niño. As weather experts cited by NASA note, storms that form farther east during El Niño years may linger in warmer waters for longer before turning toward Asia, increasing the likelihood of reaching the highest intensity category.

While satellite images show a very organized storm, communities beneath the storm face a harsher reality. Strong winds knocked down power lines and poles, and flooding and storm debris affected roads on several islands, according to NASA. Buildings were also damaged, including infrastructure related to Rota’s water supply.Emergency crews spent several days dealing with the aftermath. The U.S. Coast Guard works to eliminate navigation hazards and help restore port access once sea conditions become safer. The recovery effort begins just weeks after residents grappled with Super Typhoon Sinlaku, another devastating storm that hit the same area in April.
NASA tracks super typhoon Bavi approaching Taiwan and southern Japan
By July 8, Bavi was still a powerful typhoon, although it showed signs of gradually weakening. Satellite images released by NASA showed the storm moving westward across the Philippine Sea southeast of Taiwan.At that time, the maximum sustained wind speed was still estimated to be about 250 kilometers per hour. Forecasts show the cyclone may begin moving northwest, potentially affecting Taiwan, Japan’s southern Ryukyu Islands and parts of mainland China.Although the weather is expected to weaken over the next few days, Bawi remains a powerful system capable of producing damaging weather far from the islands that first made headlines. As forecasters continue to track its path, the storm becomes one of the strongest tropical cyclones observed globally in 2026.
