Hawaii Island Weather Update for July 7th, 2020

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


Weather Team is also closely monitoring an area approximately 1000 miles south of Hilo and a very low chance of developing into an organized storm within the next few days.


Two other areas of interest off the western coast of Mexico both 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 (Wednesday evening, July 8th).
