Gil weakens to post-tropical cyclone in Eastern Pacific as NHC monitors several systems for development
The National Hurricane Center is now monitoring Invest 90E and an area to watch off the coasts of Central America and Mexico.
Multiple tropical systems spinning across Eastern, Central Pacific
The National Hurricane Center is monitoring several tropical systems spinning across the Eastern and Central Pacific Ocean, including Tropical Storm Gil to the east of Hawaii. FOX Weather Meteorologists Haley Meier and Michael Estime have the latest forecast on Aug. 3, 2025.
The Eastern Pacific Ocean has been teeming with tropical activity over the past several weeks, and it’s showing no sign of slowing down as what was once Tropical Storm Gil spins to the east of Hawaii and more tropical trouble looms behind it.
Gil became a hurricane on Friday, and then weakened to a tropical storm over the weekend before becoming a post-tropical cyclone on Sunday as the system moved over cooler waters of the Eastern Pacific.

Post-Tropical Cyclone Gil is located more than 1,300 miles east of Hilo, Hawaii, and is moving off to the west-northwest at 18 mph.
A gradual decrease in forward speed is expected over the next few days, with a turn to the west expected by Monday.

The National Hurricane Center (NHC) said an area of disorganized showers and thunderstorms located well west-southwest of the southwestern coast of Mexico associated with a broad area of low pressure has been designated as Invest 90E.
The term "invest" is a naming convention used by the NHC to identify a system that forecasters are investigating for possible development into a tropical depression or tropical storm within the next seven days.
The NHC said Invest 90E is spinning over an area where environmental conditions are favorable for further development, and a tropical depression is likely to form over the next day or two as it moves off to the west-northwest.

Behind that, the NHC said an area of low pressure is forecast to form offshore of Central America and southern Mexico by the middle of this week.
Environmental conditions appear to be conducive for some development, and a tropical depression could form later in the week.
Right now, the NHC is giving the system a medium chance of development over the next seven days.
