Hurricane Breaking News

  • NASA Sees Hurricane Matthew over Haiti Tuesday Morning
    NASA?s MISR instrument catches hot towers -- enormous thunderheads -- from Hurricane Matthew over Haiti the morning of Oct. 4, 2016.
  • Corentin (Southern Indian Ocean)
    On January 26 at 0030 UTC (Jan. 25 at 7:30 p.m. EST), Corentin had weakened into a remnant low pressure area.
  • Victor (Southern Pacific Ocean)
    After days at hurricane-force, NASA-NOAA's Suomi NPP satellite showed that Tropical Cyclone Victor in the South Pacific Ocean was falling apart as a result of wind shear.
  • Alex (was 90L/Atlantic Low #1 - Atlantic Ocean)
    Tropical Storm Alex quickly acquired extra-tropical characteristics late on Jan. 15 as it sped northward toward Greenland in the North Atlantic Ocean.
  • Pali (was 1C - Central Pacific)
    Imagery from NOAA's GOES-West satellite has shown that former Hurricane Pali has petered out near the Equator.
  • Ula - Southern Pacific Ocean
    NOAA's GOES-West satellite and NASA's RapidScat instrument provided a look at Tropical Cyclone Ula after it became extra-tropical north of New Zealand.
  • 9C - Central Pacific
    Tropical Depression 9C formed in the Central Pacific, 30 days after the official end to the Central Pacific Hurricane Season.
  • 29W - Northwest Pacific Ocean
    Tropical Depression 29W was being battered by vertical wind shear from the day it formed and just two days later it dissipated as it reached the southern Philippines.
  • Melor (NW Pacific Ocean)
    NASA'S Multi-satellitE Retrievals for GPM (IMERG) data collected from December 12 to 17, 2015 were used to update Typhoon Melor's rainfall totals.
  • Bohale (was 05S) - Southern Indian Ocean
    NASA analyzed the rainfall rates occurring in Tropical Cyclone 05S, now renamed Tropical Cyclone Bohale.
