Hurricane Elida Forecast Discussion Number 9
2020-08-11 04:40:41| National Hurricane Center (East Pacific)
Issued at 900 PM MDT Mon Aug 10 2020 346 WTPZ44 KNHC 110240 TCDEP4 Hurricane Elida Discussion Number 9 NWS National Hurricane Center Miami FL EP092020 900 PM MDT Mon Aug 10 2020 The last few visible images before sunset showed that while Elida had developed a faint eye, recent microwave data suggest the eyewall is open on the north and northwest sides. Nonetheless, the system is still on a strengthening trend, and the latest wind speed is set to 75 kt, close to the latest TAFB/SAB intensity estimates. Elida continues moving west-northwestward at 12 kt. A mid-level ridge located over northern Mexico and the southwestern U.S. should steer the hurricane west-northwestward at about the same forward speed for another couple of days. The biggest change to report is that most of the guidance are showing this motion continuing (instead of a westward turn) or even a more poleward trend in a few days due to a mid-latitude trough. It is uncertain how vertically deep Elida will be at that point, but there is even a low-level weakness in the model fields, suggesting that a shallower Elida would still feel that trough. Consequentially, the new NHC official forecast is shifted roughly 90 n mi to the north by day 4, with continuity preventing a larger change. The forecast is still on the southern end of the guidance envelope, so further northward adjustments could still be required overnight. The hurricane has less than a day to further intensify before it then moves over cooler waters, which should start to weaken Elida. In a couple of days, a faster weakening is shown than the last advisory since the cyclone is more likely to cross over cooler waters more quickly than previously anticipated due to the northward track change, along with additional shear. Likewise, the post-tropical timing is also accelerated to day 3, which is consistent with the latest GFS/ECMWF simulated satellite data.

Issued at 900 PM MDT Mon Aug 10 2020 142 WTPZ34 KNHC 110239 TCPEP4 BULLETIN Hurricane Elida Advisory Number 9 NWS National Hurricane Center Miami FL EP092020 900 PM MDT Mon Aug 10 2020 ...ELIDA CONTINUING TO STRENGTHEN... SUMMARY OF 900 PM MDT...0300 UTC...INFORMATION ---------------------------------------------- LOCATION...20.1N 112.1W ABOUT 115 MI...185 KM NW OF SOCORRO ISLAND ABOUT 240 MI...385 KM SW OF THE SOUTHERN TIP OF BAJA CALIFORNIA MAXIMUM SUSTAINED WINDS...85 MPH...140 KM/H PRESENT MOVEMENT...WNW OR 300 DEGREES AT 14 MPH...22 KM/H MINIMUM CENTRAL PRESSURE...983 MB...29.03 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND OUTLOOK ---------------------- At 900 PM MDT (0300 UTC), the center of Hurricane Elida was located near latitude 20.1 North, longitude 112.1 West. Elida is moving toward the west-northwest near 14 mph (22 km/h), and this general motion with a gradual decrease in forward speed is expected through Thursday. Maximum sustained winds have increased to near 85 mph (140 km/h) with higher gusts. Additional strengthening is possible on Tuesday, with weakening likely on Wednesday and Thursday. Hurricane-force winds extend outward up to 15 miles (30 km) from the center and tropical-storm-force winds extend outward up to 70 miles (110 km). The estimated minimum central pressure is 983 mb (29.03 inches). HAZARDS AFFECTING LAND ---------------------- SURF: Swells generated by Elida are expected to affect portions of the coast of west-central Mexico and the southern Baja California peninsula during the next day or two. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next complete advisory at 300 AM MDT. $$ Forecaster Blake
