US government agency that tracks tropical cyclones and issues official forecasts, advisories, warnings and cone graphics for the Atlantic and eastern Pacific.
Hurricane Simon passed about 50 km off Mexico's Pacific coast on Oct. 11 as a Category 4 storm with winds near 210 km/h, NASA reported. The Sierra Madre appeared to shrink its wind field, while news reports described flooding in Manzanillo.

Long Beach inspectors red-tagged eight buildings after Tropical Storm Rachel, the third storm in six weeks to hit the Peninsula boardwalk. The city's fire department dates the collapse to the first of them in early September, so Rachel added to damage already under way.

Hurricane Simon reached Category 4 strength just off Mexico's Pacific coast on Sunday, with peak winds near 155 mph. US forecasters warned of catastrophic wind, surge and flooding across west-central Mexico near the Puerto Vallarta area.

Hurricane Isaias killed four people and cut power to at least 600,000 after reaching Florida with 105 mph winds. Its downgrade to a post-tropical cyclone leaves the flood threat in place, with NOAA warning of up to 10 inches of rain in Georgia and the Carolinas.

Hurricane Isaias, the first of the 2026 Atlantic season, is heading for a Friday-night landfall on the northern US Gulf Coast. Evacuated rigs had taken about 63% of Gulf oil output offline by Thursday, AFP reported, in a season a strong El Niño has held back.
Reality
Tropical Storm Isaias should be a hurricane by Wednesday night and a Category 2 storm by Friday morning, the US National Hurricane Center estimates. Wind shear rising sharply in the last 24 hours before landfall may cap its strength at the coast.

AL92 has a 90% chance of becoming the Atlantic's first hurricane of 2026 within 48 hours, Gizmodo reports. Gulf Coast and Florida operations can start flood prep now and hold closure decisions until the track firms up.
Reality
El Niño kept the Atlantic free of hurricanes through September for the first time in reliable records by holding wind shear high over warm water. The mark could still fall if the National Hurricane Center upgrades Tropical Storm Fay in its post-season review.
Reality
NASA counts 20 named storms and nine hurricanes in the northeastern and central Pacific by Sept. 28, against 1991-2020 averages of 13.5 and 7.4. Colorado State data put storm energy at more than double the norm, so the season is running stronger as well as busier.
Reality
Google DeepMind's WeatherNext Cyclones gives hurricane forecasters about an extra day of accuracy on average, according to a Nature study of past storms. So far it has one live season on record, and that season is what forecasters will lean on when the next storm strengthens fast.
Reality
El Niño's wind shear has helped hold the 2026 Atlantic to seven named storms and no hurricanes while the eastern Pacific logged eight hurricanes. Both oceans draw on tropical waves born over Africa, and this year those waves fared very differently on either side of Central America.

A Category 1 peak, 30 to 35 inches of projected rain, and warnings across all eight major Hawaiian islands. The wind rating described almost none of the actual exposure.

The Met Office's Julian Heming credits this year's record El Nino for the ocean heat beneath the storm. Rapid intensification happens several times a year worldwide, and the two published accounts differ on Polo's peak winds.

Brian McNoldy rebuilt a storm whose official record never held the parameters a wind field needs, producing quadrant-by-quadrant estimates every six hours for 11 days. He calls the result a best guess.
Reality
NOAA raised its below-normal odds for the 2026 Atlantic season by 20 points in August. The figure describes an ocean basin, and it says nothing about where a storm makes landfall.
Reality
Lala may or may not clip a coastline, and the Big Island's own terrain could decide it. The rain forecast of 1 to 2 feet does not move either way.
