Hawaii Island Weather Update for July 8th, 2020

HIRSC Weather Team continues to closely monitor Tropical Storm Cristina in the East Pacific Basin. Cristina is expected to become a hurricane on Thursday evening/Friday morning. Still too early to tell, if effects from Cristina will impact Hawaii Island weather.


Weather Team was closely monitoring an area of interest south of Hawaii Island, however, has since dissipated and no longer being monitored by Central Pacific Hurricane Center.


Two other areas of interest off the western coast of Mexico both still have a slight chance of becoming organized in the next few days.


HIRSC Weather Team will continue to monitor these systems as we are getting into the heart of the 2020 Hurricane Season. The next full HIRSC update on all systems will be made tomorrow evening (Thursday evening, July 9th).
