SUMMARY OF 200 PM PDT...2100 UTC...INFORMATION ---------------------------------------------- LOCATION...14.0N 139.7W ABOUT 1090 MI...1755 KM ESE OF HILO HAWAII MAXIMUM SUSTAINED WINDS...75 MPH...120 KM/H PRESENT MOVEMENT...W OR 270 DEGREES AT 9 MPH...15 KM/H MINIMUM CENTRAL PRESSURE...992 MB...29.30 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND OUTLOOK ---------------------- At 200 PM PDT (2100 UTC), the center of Hurricane Miriam was located near latitude 14.0 North, longitude 139.7 West. Miriam is moving toward the west near 9 mph (15 km/h). A turn toward the west-northwest with a decrease in forward speed is expected tonight, followed by a turn toward the northwest and north through Friday night. Maximum sustained winds have increased to near 75 mph (120 km/h) with higher gusts. Some additional strengthening is possible during the next 24 hours. Miriam is expected to begin weakening on Friday as it encounters strong upper-level winds and cooler waters. Hurricane-force winds extend outward up to 25 miles (35 km) from the center and tropical-storm-force winds extend outward up to 90 miles (150 km). The estimated minimum central pressure is 992 mb (29.30 inches). HAZARDS AFFECTING LAND ---------------------- None. NEXT ADVISORY ------------- This is the last public advisory issued by the National Hurricane Center on Miriam. Future information on this system can be found in Public Advisories issued by the Central Pacific Hurricane Center beginning at 5 PM HST, under AWIPS header HFOTCPCP3, WMO header WTPA33 PHFO, and on the web at http://www.prh.noaa.gov/cphc. $$ Forecaster Brown

Tropical Storm Miriam Forecast Discussion Number 14
2018-08-29 16:34:56| National Hurricane Center (East Pacific)
Issued at 800 AM PDT Wed Aug 29 2018 957 WTPZ45 KNHC 291434 TCDEP5 Tropical Storm Miriam Discussion Number 14 NWS National Hurricane Center Miami FL EP152018 800 AM PDT Wed Aug 29 2018 Although Miriam remains a sheared tropical cyclone, recent geostationary satellite data and a 1002 UTC AMSR2 microwave overpass indicates that there has been some improvement in the structure of the cyclone. The microwave data showed an increase in banding over the eastern portion of the circulation and less separation between the convection and the low-level center. Therefore, the initial intensity is increased to 60 kt, which is a blend of the most recent subjective Dvorak classifications and objective T-numbers from UW/CIMSS. The northwesterly shear over the cyclone appears to have abated slightly, and a further slight reduction in shear could allow Miriam to reach hurricane strength within the next 24-36 h. Most of the intensity guidance agrees, and the NHC intensity forecast has been increased slightly for the first 36 h. After that time, increasing shear and cooler waters are expected to cause Miriam to weaken fairly quickly and the system is forecast to become a remnant low by day 4. Miriam continues to move westward or 275/10 kt. The cyclone is approaching the western edge of the subtropical ridge, and the global models indicate that Miriam will slow down and turn west-northwestward very soon. By Thursday, a large mid- to upper-level trough to the northeast of the Hawaiian Islands is expected to cause Miriam to turn northwestward, then northward through 72 hours. At days 3 and beyond, there continues to be significant model differences with the ECMWF still taking Miriam faster and much farther northward, while the GFS moves a much weaker Miriam westward. Since Miriam is forecast to weaken and become a shallow system around that time, the NHC forecast leans toward the more westward scenario, but is not as far south and west as the GFS. The new NHC track is south of the various consensus aids at day 5, and is in best agreement with the GFS ensemble mean and UKMET model.
