For the North Atlantic...Caribbean Sea and the Gulf of America:
East of the Leeward Islands (Remnants of Dolly):
A tropical wave, the remnants of Tropical Storm Dolly, are located
several hundred miles east of the Leeward Islands. Redevelopment of
this system is unlikely while it moves westward to
west-northwestward near 25 mph. The wave could bring locally heavy
rains and gusty winds to portions of the Leeward Islands, the Virgin
Islands and Puerto Rico over the next several days.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...10 percent.
Northeastern and North-Central Gulf of America:
Disorganized cloudiness and showers over portions of the
northeastern and north-central Gulf of America are associated with a
weak area of low pressure. Development, if any, of this system is
expected to be slow while it remains nearly stationary for the next
several days.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...10 percent.

For the eastern and central North Pacific east of 180 longitude:
Active Systems:
The National Hurricane Center is issuing advisories on Tropical
Storm Karina, located well southwest of the southern tip of the Baja
California Peninsula, and on Tropical Storm Lowell, located well
east-southeast of the Hawaiian Islands.
Well Offshore of Southwestern Mexico:
An area of disturbed weather, associated with a tropical wave, is
located well to the south of southwestern Mexico. Environmental
conditions appear favorable for gradual development of this system,
and a tropical depression is likely to form early next week while
it moves west-northwestward to northwestward at 10 to 15 mph.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 7 days...high...80 percent.
Central Pacific:
An area of low pressure could form well south or southwest of the
Hawaiian Islands in a few days. Some gradual development is possible
thereafter and a tropical depression could form during the middle
part of next week while the system moves slowly west-northwestward,
well offshore of the Hawaiian Islands.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...medium...40 percent.

DISCUSSION AND OUTLOOK ---------------------- At 800 PM PDT (0300 UTC), the center of Tropical Storm Karina was located near latitude 14.2 North, longitude 116.3 West. Karina is moving toward the northwest near 12 mph (19 km/h), and this general motion is expected to continue over the next day or so, followed by a more westward turn. Maximum sustained winds are near 65 mph (100 km/h) with higher gusts. Strengthening is forecast during the next several days. Karina is forecast to become a hurricane by early Saturday and could become a major hurricane early next week. Tropical-storm-force winds extend outward up to 230 miles (370 km) from the center. The estimated minimum central pressure is 988 mb (29.18 inches). HAZARDS AFFECTING LAND ---------------------- SURF: Swells generated by Karina will begin to affect portions of the coast of southwest Mexico and the Baja California Peninsula this weekend. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.

Tropical Storm Karina Forecast Discussion Number 6
Issued at 800 PM PDT Fri Aug 28 2026 000 WTPZ41 KNHC 290252 TCDEP1 Tropical Storm Karina Discussion Number 6 NWS National Hurricane Center Miami FL EP112026 800 PM PDT Fri Aug 28 2026 Visible satellite imagery continues to show Karina with distinct, well-organized spiral banding around a central dense cloudy inner core. The latest subjective intensity estimate of T3.5/55 kt from TAFB, is lining up well with the objective intensity estimates of 50 to 60 kt from UW-CIMSS. Because of this, the initial intensity was maintained at 55 kt. Karina is on a northwestward heading of 310/10 kt. This should continue through the next 24 h or so as ridging will build over the Southwestern United States. Karina is then forecast to slow slightly and be steered in a more westerly direction this weekend as a mid-level trough first erodes the aforementioned ridge, and another ridge over the central North Pacific quickly builds southeastward in its place. The overall track of Karina was shifted a bit farther south from the previous advisory, following the HCCA guidance, but the reliable guidance remains in good agreement through the early portion of the forecast. Model spread increases significantly thereafter reducing confidence of Karina's exact track toward the latter end of the forecast period. The SHIPS guidance remains largely unchanged, still showcasing a favorable environment for intensification over the next 60 h or so. Given the light shear, warm SSTs, and moisture-laden atmosphere, Karina has all the necessary ingredients conducive to significantly strengthen to major hurricane status. The latest guidance from Google DeepMind now features over 80 percent of the ensemble members showing Karina becoming a major hurricane. The SHIPS diagnostics show environmental conditions becoming less conducive for strengthening after the weekend and weakening becoming becoming increasingly likely early next week. Slight adjustments to the intensity forecast have been made to reflect the guidance.

Tropical Storm Lowell Forecast Discussion Number 6
Issued at 500 PM HST Fri Aug 28 2026 347 WTPZ42 KNHC 290241 TCDEP2 Tropical Storm Lowell Discussion Number 6 NWS National Hurricane Center Miami FL EP122026 500 PM HST Fri Aug 28 2026 Lowell remains a sheared tropical cyclone this afternoon. Moderate easterly vertical wind shear continues to displace the bulk of the convection over and west of the low-level circulation center. There has been little evidence of strengthening during the past several hours, and a blend of the latest objective intensity estimates and subjective Dvorak intensity estimate from TAFB support holding the initial intensity at 40 kt for this advisory. The cyclone continues to move slowly westward, with an initial motion of about 275/5 kt. A low- to mid-level ridge is forecast to strengthen north of the cyclone during the next couple of days, which should cause the cyclone to continue westward with a gradual increase in forward speed. This general westward motion is expected to continue through the weekend and into early next week. Track forecast uncertainty increases considerably thereafter due in part to the potential influence on the steering flow from TS Karina to its northeast. There remains considerable spread in the guidance, particularly in forward speed, with the multi-model consensus (HCCA) and Google DeepMind ensemble mean generally faster than the GFS and ECMWF solutions. In addition to the along-track spread, the cross-track spread also increases considerably by day 5. Given these differences, the latest NHC track forecast reflects a blend of the previous forecast, Google DeepMind ensemble mean, and HCCA. The easterly vertical wind shear currently affecting Lowell is forecast to hold into the weekend, then steadily decrease by the latter half of the weekend, which should allow the cyclone to become better organized and gradually strengthen. However, the current sheared structure and nearby mid- to upper-level dry air should temper the rate of intensification in the short term. Environmental conditions are forecast to become more favorable thereafter, and a faster rate of strengthening is possible beginning by early next week. The intensity forecast becomes more uncertain later in the period due to Lowell's potential interaction with Karina. A faster westward track would likely keep the cyclones sufficiently separated and allow Lowell to continue strengthening, while a slower solution could expose Lowell to stronger shear associated with outflow from Karina. The latest NHC intensity forecast is similar to the previous advisory and continues to show Lowell becoming a hurricane in about 60 h.
