345 WTPZ45 KNHC 182034 TCDEP5 Hurricane Erick Discussion Number 9 NWS National Hurricane Center Miami FL EP052025 300 PM CST Wed Jun 18 2025 An Air Force Reconnaissance aircraft completed its mission into Erick this morning and found 93-kt flight-level winds at 700 mb along with a dropsonde central pressure of 971 mb around 17Z. The recon data showed strengthening in between the 1530Z fix and the 17Z fix. An eye has been present in visible and infrared satellite imagery since about 15Z this morning, and recent satellite imagery shows the eye continuing to become more circular with warming eye temperatures. The eye is nearly completely surrounded by a large area of convective cloud tops colder than -70C. As a result, satellite intensity estimates have been increasing quickly. The 18Z subjective Dvorak estimates from TAFB and SAB range from 90-102 kt. Recent objective intensity estimates from UW-CIMSS are in the 95-100 kt range. Based on a blend of the data, the initial intensity is estimated to be 95 kt, and this might be a bit conservative. The initial motion estimate is northwestward, or 315/8 kt. This general motion, along with perhaps a slight acceleration, is expected through landfall, which is forecast to occur early Thursday morning along the southern coast of Mexico. Erick has been moving to the right of the previous official forecast, and as a result, the new guidance shows landfall slightly to the east of the previous track. The new NHC track forecast is shifted eastward, close to the latest TVCE and HCCA consensus aids. Confidence in the track forecast is high. Erick has been rapidly strengthening for the past 12 hours, and given the extremely favorable atmospheric and oceanic conditions along Erick's forecast track, further intensification in the short term appears very likely. The 12Z HAFS models and the 18Z SHIPS guidance have Erick becoming a major hurricane soon. The various SHIPS Rapid Intensification indices all show greater than a 70 percent chance of 20 kt strengthening in the next 12 h. The new NHC forecast shows 110 kt at 12 h, which is at the high end of the intensity guidance suite. There is a possibility that Erick could strengthen more than forecast. The next Air Force Reconnaissance aircraft is scheduled to be in the hurricane in a few hours, around 2330 UTC today. KEY MESSAGES: 1. Erick continues to rapidly intensify and is expected to be a major hurricane when it reaches the coast of western Oaxaca or eastern Guerrero within the hurricane warning area late tonight or early Thursday. Devastating wind damage is possible where the core of the storm moves onshore. Weather conditions are already deteriorating, and preparations to protect life and property should be rushed to completion before sunset. 2. Erick will produce heavy rainfall across portions of Central America and Southwest Mexico through this week. Life-threatening flooding and mudslides are likely, especially in areas of steep terrain. 3. A dangerous, life-threatening storm surge is expected to produce coastal flooding near and to the east of where the center crosses the coast, in areas of onshore winds. The surge will be accompanied by large and destructive waves.
