For the eastern and central North Pacific east of 180 longitude:
Active Systems: The National Hurricane Center is issuing advisories on recently upgraded Tropical Storm Kiko, located in the east Pacific basin far southwest of the southern tip of the Baja California peninsula.
South of Southern Mexico: A tropical wave is producing a large area of disorganized showers and thunderstorms south of southern Mexico. An area of low pressure is expected to form from this system within the next day or two, and it is likely to become a tropical depression by the middle of this week while moving west-northwestward or northwestward at 10 to 15 mph just offshore of the southwestern coast of Mexico. * Formation chance through 48 hours...medium...50 percent. * Formation chance through 7 days...high...80 percent.

Tropical Storm Kiko Discussion Number 2
NWS National Hurricane Center Miami FL EP112025
500 AM HST Sun Aug 31 2025
Satellite imagery and a recent AMSR2 pass show a curved band
wrapping around the western semicircle of the cyclone, along with a
burst of deep convection developing over the center where cloud tops
are near -80 C. The convective banding now wraps more than halfway
around the circulation, which, along with Dvorak current intensity
estimates of 2.5/35 kt from TAFB and up to 3.0/45 kt from SAB,
supports upgrading the system to Tropical Storm Kiko with an initial
intensity of 35 kt.
Kiko is moving westward near 8 kt, or 270/8 kt, steered by a strong
subtropical ridge positioned to its north. This ridge is expected to
remain in place throughout the 5-day forecast period, maintaining a
general westward motion across the eastern Pacific and into the
central Pacific basin by late this week. The official track forecast
is nearly identical to the previous forecast and remains close to
the consensus aids.
Environmental conditions of warm sea surface temperatures, moist
mid-level air, and low vertical wind shear favor steady
strengthening during the next couple of days. Kiko is forecast to
reach hurricane intensity by around 48 hours (Tuesday). Thereafter,
the cyclone’s track near the 26 C isotherm, along with the potential
entrainment of mid-level dry air, could limit any additional
significant intensification. Also, any deviation of the track
slightly to the right of the forecast path could place the system
over cooler waters and further inhibit strengthening. The intensity
forecast is near the middle to higher end of the guidance envelope
through midweek, then trends closer to the consensus thereafter.
