Monthly Tropical Weather Summary
NWS Central Pacific Hurricane Center Honolulu HI
335 AM HST Thu May 1 2025

This is the last Central Pacific Hurricane Center (CPHC)
Tropical Weather Summary (TWS) text product that will be issued for
the central North Pacific basin. The tropical cyclone statistics
from the TWS will be found on hurricanes.gov beginning with the 2025
hurricane season. This change will allow for more frequent updates
to the statistics and the addition of graphics and links to
supporting information that this text only format cannot support.
An account of tropical cyclone names, classification (i.e., tropical
depression, tropical storm, or hurricane), and maximum sustained
wind speed will be found on hurricanes.gov at this url beginning
around June 1:

A sample webpage is provided here, with the "2023 Atlantic Summary
Table (PDF)" example linked below the Tropical Cyclone Reports
(TCRs):

https://www.nhc.noaa.gov/data/tcr/index.php?season=2023&basin=atl

This information will be updated no less frequently than monthly
during the hurricane season and will be updated after the season's
TCRs are completed to document the official record of the season's
tropical cyclone activity. Previously, the statistics and data in
the TWS were based on real-time operational assessments and were
not updated when the season's TCRs were complete. The new web-based
format allows the information to be updated once the post-analysis
for the season is complete.
