modismur sstNASA Earth Observatory/Michala GarrisonNASA Earth Observatory/Michala Garrisonmodis mur sstNASA Earth Observatory/Michala GarrisonNASA Earth Observatory/Michala Garrisonmodismur sstCurtain Toggle 2-UpImage DetailsAfter rapidly intensifying, Hurricane Polo spins off Mexico’s Pacific coast on September 23, 2026 (left), over unusually warm waters (right). NASA Earth Observatory images by Michala Garrison, using data from the MODIS (Moderate Resolution Imaging Spectroradiometer) on NASA's Aqua satellite and the MUR SST (Multiscale Ultrahigh Resolution Sea Surface Temperature) project.In mid-September 2026, Hurricane Polo began as a tropical disturbance off the Pacific coast of Mexico. By September 20, it was organized enough to qualify as a tropical depression, and by the next day it was a tropical storm.

From there, Polo launched into a period of rapid intensification that left meteorologists searching for adjectives strong enough to convey what was happening. Some described the storm's rate of intensification and strength as "jaw-dropping," others as "astonishing," and others as "absolute insanity."  

"Polo went through a period of what can only be described as explosively rapid intensification," said Gary Partyka, an atmospheric scientist with the Global Modeling and Assimilation Office (GMAO) at NASA’s Goddard Space Flight Center, in an email. "This was RAPID, rapid intensification."

The storm was in an environment that was "near perfect" for strengthening, Partyka said, characterized by weak wind shear, high moisture, warmer ocean temperatures, and high levels of atmospheric instability.

Several observers leaned on extreme rapid intensification - a technical classification meaning the storm's wind speeds increased at least 60 knots (111 kilometers or 69 miles per hour) within a 24-hour period. By September 22, the storm’s maximum sustained wind speed had risen by 90 knots (167 kilometers per hour or 104 miles per hour) within 24 hours, hitting category 5 strength. In its normally staid forecast discussions, the National Hurricane Center called the intensification "truly remarkable."

When NOAA's Hurricane Hunter aircraft flew over the storm on September 22, researchers estimated winds of nearly 285 kilometers (180 miles) per hour. That would make it the third-strongest storm on record in the eastern Pacific by maximum sustained winds and the fastest on record to go from a tropical depression to a category 5 storm, according to some analysts.

On the afternoon of September 23, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite captured this image (left), Polo was churning off the coast of Guerrero, southwest of Acapulco. With maximum sustained winds of 230 kilometers (145 miles) per hour, the storm was category 4 strength when the image was acquired, having undergone an eyewall replacement cycle that weakened it slightly.

* WHAT...Up to one foot of inundation above ground level expected in low-lying areas near shorelines and tidal waterways.

The water also may struggle to vacate the area after the high tides given persistent strong northeast winds. The greatest risk for coastal flooding appears to be setting up south of Boston and onto the Cape and Islands. In addition...the long duration of northeast winds coupled with large waves over multiple high tide cycles will result in areas of severe beach erosion for a prolonged period.
