Hawaii Island Weather Update for July 11th, 2020

HIRSC Weather Team is continuing to watch two disturbances in the East Pacific. The first disturbance, Tropical Storm Cristina, is moving a track as it begins to slowly dissipate as it moves west. The only impact expected for Hawaii Island weather is an increase of windward and mauka showers moving in with the trade wind flow later next weekend.


The second disturbance, an area of interest that crossed into the East Pacific from Central America has a high chance of becoming an organized storm in the next 5 days. We will closely monitor this disturbance as it becomes more organized in the coming days.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
1100 AM PDT Sat Jul 11 2020

For the eastern North Pacific...east of 140 degrees west longitude:

The National Hurricane Center is issuing advisories on Tropical 
Storm Cristina, located several hundred miles west-southwest of the 
southern tip of the Baja California peninsula.

1. A low pressure system located a couple of hundred miles southeast 
of Acapulco, Mexico, has become a little better defined this 
morning. Although upper-level winds are currently only marginally 
conducive for development of a tropical cyclone, environmental 
conditions are expected to become more favorable for the formation
of a tropical depression in two or three days while the system 
moves quickly west-northwestward to westward, well south of the 
coast of Mexico.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...high...80 percent.
