000 WTPZ33 KNHC 120835 TCPEP3 BULLETIN Tropical Depression Thirteen-E Advisory Number 3 NWS National Hurricane Center Miami FL EP132025 300 AM CST Fri Sep 12 2025 ...DEPRESSION REMAINS POORLY ORGANIZED OFF THE COAST OF SOUTHWESTERN MEXICO... SUMMARY OF 300 AM CST...0900 UTC...INFORMATION ---------------------------------------------- LOCATION...16.5N 100.8W ABOUT 100 MI...160 KM SSE OF ZIHUATANEJO MEXICO MAXIMUM SUSTAINED WINDS...35 MPH...55 KM/H PRESENT MOVEMENT...WNW OR 295 DEGREES AT 12 MPH...19 KM/H MINIMUM CENTRAL PRESSURE...1007 MB...29.74 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. Interests along the coast of southwestern Mexico should monitor the progress of this system. DISCUSSION AND OUTLOOK ---------------------- At 300 AM CST (0900 UTC), the center of Tropical Depression Thirteen-E was located near latitude 16.5 North, longitude 100.8 West. The depression is moving toward the west-northwest near 12 mph (19 km/h), and this general motion is expected to continue during the next couple of days. On the forecast track, the center of the depression will move parallel to, but offshore of, the southwestern coast of mainland Mexico through early Saturday. Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Slow strengthening is expected during the next couple of days, and the system is forecast to become a tropical storm later today. The estimated minimum central pressure is 1007 mb (29.74 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Tropical Depression Thirteen-E will lead to rainfall totals of 2 to 4 inches, with local amounts of 6 inches, across southern Mexico through Sunday. This brings a risk of flash flooding, especially in areas of higher terrain. For a complete depiction of forecast rainfall and flash flooding associated with Tropical Depression Thirteen-E, please see the National Weather Service Storm Total Rainfall Graphic, available at hurricanes.gov/graphics_ep3.shtml?rainqpf WIND: Gusty winds are possible along portions of the southwestern coast of Mexico from west of Acapulco to Manzanillo during the next day or so. NEXT ADVISORY ------------- Next complete advisory at 900 AM CST. $$ Forecaster Reinhart

000 WTPZ43 KNHC 120836 TCDEP3 Tropical Depression Thirteen-E Discussion Number 3 NWS National Hurricane Center Miami FL EP132025 300 AM CST Fri Sep 12 2025 The depression remains poorly organized tonight, with only small areas of convection bursting to the west of the estimated low-level center. Recent scatterometer data and surface observations indicate the circulation remains very small. While believable scatterometer winds up to about 30 kt were noted offshore in the northern semicircle of the circulation, observations from the Acapulco International Airport indicated these winds did not reach the coast when the system made its closest approach earlier tonight. Since the overall satellite presentation has slightly worsened since the earlier scatterometer pass, the initial intensity is held at 30 kt. The initial motion is west-northwestward (295/10 kt), and the system should maintain this heading during the next couple of days while being steered by a mid-level ridge centered over northern Mexico. Later this weekend through early next week, the system is forecast to move toward the northwest as it rounds the southwestern portion of the steering ridge. The NHC track forecast through 60 h has been nudged slightly northward this cycle, in agreement with the latest multi-model consensus aids. In the near term, only modest strengthening is forecast due to the system's close proximity to land. Some models, including the GFS and ECMWF, completely lose the circulation later today. But if the system remains offshore and survives its close passage to the southwestern coast of Mexico, the environment should become somewhat more favorable for strengthening with weaker shear conditions over warm waters. Overall, the intensity guidance trended much lower this cycle. The updated NHC intensity forecast reflects this trend, but remains on the high end of the guidance envelope. Future downward adjustments may be necessary, and it cannot be ruled out that the system dissipates before the end of the 5-day forecast period. Key Messages: 1. Heavy rainfall associated with Tropical Depression Thirteen-E will impact southern and southwestern Mexico through Sunday, which could result in flash flooding, particularly in areas of higher terrain. 2. The depression is forecast to become a tropical storm today while moving parallel to the southwestern coast of Mexico. While the strongest winds are expected to remain offshore, gusty winds are possible along portions of the southwestern coast of Mexico from Acapulco to Manzanillo during the next day or so. Interests in these areas should monitor the progress of this system.
