Tropical Weather Outlook
NWS National Hurricane Center Miami FL
1100 PM PDT Fri Aug 1 2025

For the eastern and central North Pacific east of 180 longitude:

Active Systems:
The National Hurricane Center is issuing advisories on Hurricane
Gil, located well west-southwest of the southern Baja California
peninsula. The Central Pacific Hurricane Center has issued its final
advisory on Tropical Depression Iona, which is now located west of
the International Date Line, well west-southwest of the Hawaiian
Islands. Future advisories will be issued by RSMC Tokyo, Japan. For
U.S. interests, refer to Department of Defense warnings issued by
the Joint Typhoon Warning Center in Honolulu, Hawaii.

Western East Pacific:
An area of low pressure is expected to form well southwest of
southwestern Mexico within the next day or two. Environmental
conditions appear conducive for some gradual development of this
system, and a tropical depression is likely to form late this
weekend or early next week as the system moves west-northwestward at
10 to 15 mph.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 7 days...high...80 percent.

South of Southern Mexico:
An area of low pressure is forecast to form offshore of the coast of
Central America and southern Mexico by the middle part of next week.
Thereafter, environmental conditions appear conducive for some
development, and a tropical depression could form late next week as
the system moves generally west-northwestward at 10 to 15 mph.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...medium...40 percent.

Issued at 500 PM HST Fri Aug 01 2025 000 WTPZ42 KNHC 020248 TCDEP2 Hurricane Gil Discussion Number 8 NWS National Hurricane Center Miami FL EP072025 500 PM HST Fri Aug 01 2025 Gil appears to have rid itself of the intrusion of dry air it had been dealing with earlier in the day. The center is now embedded within a Central Dense Overcast, and as a result, subjective satellite estimates are a consensus T4.0/65 kt from TAFB and SAB. Several objective estimates from UW-CIMSS are at that level or higher, so Gil is therefore upgraded to a 65-kt hurricane. Gil is moving faster toward the west-northwest, now 295/17 kt. Strong mid-level ridging is expected to persist to the north of the hurricane, which should cause Gil to continue moving quickly toward the west-northwest through much of the weekend. A slower forward motion with a turn toward the west is forecast by Monday as the weakening cyclone is steered by lower-level flow. The new NHC track forecast is just a touch south of the previous prediction, leaning toward the HCCA and AI models. Gil only has a small window for continued strengthening since cooler sea surface temperatures lie ahead. The NHC intensity forecast allows for a bit more strengthening through 12 hours, but then fast weakening is expected thereafter due to the cold waters. In fact, model-simulated satellite images indicate Gil will likely lose its deep convection in about 48 hours, and the NHC forecast shows it becoming post-tropical at that time. Because of Gil's fast motion, the decrease in its winds are likely to lag the loss of convection, and the 45-kt forecast intensity at 48 hours is higher than is typical for when an eastern Pacific tropical cyclone becomes post-tropical. Gil is expected to open up into a trough by day 5, which is supported by most of the global model guidance.

For the eastern and central North Pacific east of 180 longitude:

Active Systems:
The National Hurricane Center is issuing advisories on Tropical
Storm Iona, located in the central Pacific basin well west-southwest
of the Hawaiian Islands, and Tropical Storm Gil, located well

Central East Pacific:
An area of low pressure is expected to form well southwest of
southwestern Mexico within the next day or two. Environmental
conditions appear conducive for some gradual development of this
system, and a tropical depression is likely to form late this
weekend or early next week as the system moves west-northwestward at
10 to 15 mph.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 7 days...high...80 percent.

South of Southern Mexico:
An area of low pressure is forecast to form offshore of the coast of
Central America and southern Mexico by the middle part of next week.
Thereafter, environmental conditions appear conducive for some
development as the system moves generally west-northwestward at 10
to 15 mph.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...30 percent.

Issued at 1100 AM HST Fri Aug 01 2025 736 WTPZ42 KNHC 012039 TCDEP2 Tropical Storm Gil Discussion Number 7 NWS National Hurricane Center Miami FL EP072025 1100 AM HST Fri Aug 01 2025 Gil has slightly strengthened over the past few hours. A scatterometer pass from 1710 UTC showed an area of near 50 kt vectors in the northeastern quadrant of the storm. More recent geostationary satellite data shows fragmented convection, with a curved band wrapping around the southern semicircle. The imagery suggests Gil is experiencing a dry air intrusion wrapping around the storm's core. Based on the ASCAT data (accounting for instrument undersampling) and a blend of the latest subjective Dvorak estimates the initial intensity is increased slightly to 60 kt. The initial motion is 290/15 kt. The track forecast reasoning remains unchanged. Gil should continue a west-northwestward motion along the southern periphery of a mid-level ridge for the next few days. As the storm weakens, a turn to the west is forecast around day 4. The NHC track prediction is essentially unchanged from the previous cycle's forecast. Gil is currently crossing a cooling gradient of the sea surface temperatures and nearing the 26 degree Celsius isotherm. Therefore, the storm's chances for any significant strengthening are quickly diminishing. Beyond 12 hours, global models predict increasing shear and a dry and stable airmass will steadily weaken the storm for the remainder of the forecast period. The latest official intensity forecast lies near the various consensus aids. Gil is still expected to become a post-tropical cyclone by the end of weekend.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
1100 AM PDT Fri Aug 1 2025

For the eastern and central North Pacific east of 180 longitude:

Active Systems:
The National Hurricane Center is issuing advisories on Tropical
Storm Iona, located in the central Pacific basin well west-southwest
of the Hawaiian Islands and Tropical Storm Gil, located well
west-southwest of the southern Baja California peninsula.

Central East Pacific:
An area of low pressure is expected to form well southwest of
southwestern Mexico within the next day or two. Environmental
conditions appear conducive for some gradual development of this

weekend or early next week as the system moves west-northwestward at
10 to 15 mph.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 7 days...high...80 percent.

South of Southern Mexico:
An area of low pressure is forecast to form offshore of the coast of
Central America and southern Mexico by the middle part of next week.
Thereafter, environmental conditions appear conducive for some
development as the system moves generally west-northwestward at 10
to 15 mph.
* Formation chance through 48 hours...low...near 0 percent.
