Tropical Cyclone Outlook for July 21st, 2020

The HIRSC - Weather Team is continuing to monitor two disturbances in the East Pacific:


Tropical Depression Seven-E continues to churn in the East Pacific and is on a path to become a remnant low in the next few days. No weather impacts on Hawaii Island are expected related to Seven-E.


Tropical Storm Douglas continues to churn in the East Pacific as well. Based on the latest weather forecast modes, Douglas is expected to strengthen into a Hurricane Tuesday evening into Wednesday (July 22nd). The center of Douglas is located 2168 miles southeast of Hilo, Hawaii Island.


Still, too early to tell the weather impacts to Hawaii Island, HIRSC Team will continue to monitor Douglas and provide an update late Tuesday evening (July 21st) on the latest forecast and also actions the HIRSC Team will be taking regarding Tropical Storm Douglas.
