000 WTPZ41 KNHC 021434 TCDEP1 Hurricane Flossie Discussion Number 14 NWS National Hurricane Center Miami FL EP062025 800 AM MST Wed Jul 02 2025 Satellite imagery shows that the inner core of Flossie has started to degrade this morning, and the eye has become more ragged and cloud filled. An AMSR2 microwave pass around 0916 UTC shows that the northern eyewall has started to deteriorate, and is open on the northern side. This suggest a weakening trend has begun, and Flossie has likely reached peak intensity. While the system has peaked, deep cold convection continues to wrap around the southern and eastern side of the system. Satellite intensity estimates range from 90-100 kt. Given the latest satellite trends and using a blend of the estimates, the initial intensity is set to 95 kt for this advisory. Flossie continues to move toward the west-northwest or 300/9 knots. This general motion is expected to continue throughout the remainder of the forecast period, towards a weakness in the mid-level ridge. The latest NHC track forecast was nudged slightly to the right of the previous, and lies near the HCCA corrected consensus. A steady to rapid weakening trend is expected to begin today. Along the forecast track, Flossie will continue to move into cooler sea surface temperatures and drier mid-level air. Thus, the NHC intensity forecast shows a little quicker weakening trend compared to the previous, and lies near the simple intensity consensus. Flossie expected to become a post-tropical low by 36 hours, with dissipation following by 96 hours.

974 WTPZ41 KNHC 020835 TCDEP1 Hurricane Flossie Discussion Number 13 NWS National Hurricane Center Miami FL EP062025 200 AM MST Wed Jul 02 2025 Flossie remains an impressive hurricane early this morning, although the well-defined eye evident earlier tonight has become less distinct and somewhat cloud filled in recent satellite images. The latest subjective Dvorak intensity estimates were T5.5/102 knots from TAFB and T5.0/90 knots from SAB. Meanwhile, the objective intensity estimates ranged from 96 to 107 knots at 06z. Based on a blend of these data, the initial intensity will be held at 100 knots for this advisory. Flossie is heading toward the west-northwest or 300/9 knots. This general motion is expected to continue during the next several days as the cyclone is steered into a weakness in the mid-level ridge to the northwest of the system. A turn more to the west is expected beyond 48 hours as the increasingly shallow system becomes steered by the low-level trade wind flow. The track forecast has been shifted slightly to the left of the previous advisory to align with the latest consensus guidance trends, and closely follows a blend of the latest GDMI, FSSE and TVCE consensus aids. The window for additional strengthening appears to be closing quickly, as Flossie begins to move over slightly less conducive waters for intensification with sea surface temperatures now around 27C. Wind shear remains light and mid-level moisture remains high during the next 12 hours, so with the system remaining over adequately warm water, the intensity should change little. Flossie will move over much cooler water between 12 and 24 hours, and into a drier mid-level environment. This should result in rather rapid weakening of the system, with Flossie expected to become a post-tropical low by 48 hours, with dissipation following by 96 hours. The intensity forecast has been adjusted to show a bit faster weakening of the system which is in line with the latest intensity consensus aids. KEY MESSAGES: 1. Outer bands of Hurricane Flossie continue to bring locally heavy rainfall to coastal portions of the Mexican states of Michoacán, Colima, and Jalisco into Wednesday. Localized flash flooding is possible. 2. Large swells generated by Flossie will cause life-threatening surf and rip current conditions along portions of the coast of southwestern Mexico, and the Baja California peninsula during the next few days.

132 WTPZ41 KNHC 020252 TCDEP1 Hurricane Flossie Discussion Number 12 NWS National Hurricane Center Miami FL EP062025 800 PM MST Tue Jul 01 2025 After briefly filling, the ragged eye of Flossie has reappeared on geostationary satellite imagery. An SSMIS microwave satellite image from 0133 UTC showed that the northern eyewall was slightly eroded. Since then, infrared satellite observations have shown continuous deep convective bursts in the northeastern quadrant. Objective and subjective satellite intensity estimates range between 90 to 107 kts. The initial intensity is nudged up to 100 kt based on a blend of these estimates. Flossie has about a 12-24 hour window to strengthen in conducive environmental conditions. Thereafter, global models suggest drier air and moderate vertical wind sheer could beginning disrupting the circulation on Wednesday. These conditions should coincide with the storm crossing the 26 degree isotherm and moving over cooler waters which should hasten weakening. Flossie is now forecast to become a post-tropical cyclone in 48 h. The hurricane is moving west-northwestward at 8 kt. The track forecast reasoning has not changed. Flossie should continue moving west-northwestward or northwestward toward a weakness in the subtropical ridge for the next few days. As the system becomes more shallow, it should gradually turn westward in the low-level flow. Only minor changes have been made to the latest official forecast. KEY MESSAGES: 1. Outer bands of Hurricane Flossie continue to bring locally heavy rainfall to coastal portions of the Mexican states of Michoacán, Colima, and Jalisco into Wednesday. Localized flash flooding is possible. 2. Tropical storm conditions are expected in portions of the tropical storm warning area in southwestern Mexico for the next few hours.

280 WTPZ41 KNHC 012032 TCDEP1 Hurricane Flossie Discussion Number 11 NWS National Hurricane Center Miami FL EP062025 200 PM MST Tue Jul 01 2025 Flossie continues to intensify this afternoon, with deep cold convection wrapping around the eyewall. GOES satellite visible imagery shows an eye has been trying to clear out and warm throughout the day. The latest subjective and objective satellite intensity estimates are between 90-95 kt. Based on the latest trends and these estimates, the initial intensity is set to 95 kt for this advisory. The initial motion is 300/9 kt. A general west-northwest to northwestward motion is forecast over the next few days as Flossie moves toward a weakness in the subtropical ridge. As the system begins to weaken, a more westward motion is anticipated as the storm is steered by the low-level wind flow. The latest NHC track forecast track lies near the previous, which is near the HCCA corrected consensus. Flossie will remain in a favorable environment, with warm SSTs, plentiful moisture, and weak wind shear for the next 12-24 hours. Along the forecast track the system will be moving into increasingly cooler SSTs and drier air in about 24 h. The latest NHC forecast is for some additional strengthening in the short term, which is above all available guidance. Afterwards, Flossie is expected to rapidly weaken, with the system becoming post-tropical by 72 h, and a remnant low by 96 h and dissipated by day 5. The latest NHC intensity forecast remains at the high end of the guidance in the short term, before trending towards the consensus aids as the system weakens. KEY MESSAGES: 1. Outer bands of Hurricane Flossie continue to bring locally heavy rainfall to coastal portions of the Mexican states of Michoacán, Colima, and Jalisco into Wednesday. Localized flash flooding is possible. 2. Tropical storm conditions are expected in portions of the tropical storm warning area in southwestern Mexico for the next few hours.
