Hurricane Elida Public Advisory Number 12
2020-08-11 22:35:20| National Hurricane Center (East Pacific)
Issued at 200 PM PDT Tue Aug 11 2020 213 WTPZ34 KNHC 112035 TCPEP4 BULLETIN Hurricane Elida Advisory Number 12 NWS National Hurricane Center Miami FL EP092020 200 PM PDT Tue Aug 11 2020 ...ELIDA EXPECTED TO WEAKEN TONIGHT... SUMMARY OF 200 PM PDT...2100 UTC...INFORMATION ---------------------------------------------- LOCATION...22.1N 115.4W ABOUT 355 MI...570 KM W OF THE SOUTHERN TIP OF BAJA CALIFORNIA MAXIMUM SUSTAINED WINDS...100 MPH...155 KM/H PRESENT MOVEMENT...WNW OR 300 DEGREES AT 15 MPH...24 KM/H MINIMUM CENTRAL PRESSURE...975 MB...28.80 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 Elida was located near latitude 22.1 North, longitude 115.4 West. Elida is moving toward the west-northwest near 15 mph (24 km/h), and this general motion should continue with some decrease in forward speed through Wednesday night. A turn toward the northwest is expected on Thursday. Maximum sustained winds are near 100 mph (155 km/h) with higher gusts. Rapid weakening is expected to begin tonight as Elida moves over colder water, and the cyclone is expected to weaken to a tropical storm Wednesday or Wednesday night and degenerate to a remnant low Thursday or Thursday night. 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 975 mb (28.80 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 800 PM PDT. $$ Forecaster Beven

Tropical Depression Eleven Forecast Discussion Number 1
2020-08-11 22:32:51| National Hurricane Center (Atlantic)
Issued at 500 PM AST Tue Aug 11 2020 000 WTNT41 KNHC 112032 TCDAT1 Tropical Depression Eleven Discussion Number 1 NWS National Hurricane Center Miami FL AL112020 500 PM AST Tue Aug 11 2020 Visible satellite imagery and ASCAT-C data from earlier in the day have shown that the area of low pressure NHC has been monitoring over the tropical Atlantic has developed a less-elongated circulation with a well-defined center. For the most part, deep convection has persisted with the system since about this time yesterday, save a brief period of warming cloud tops this morning. The low now meets the criteria of a tropical cyclone, and advisories have been initiated on Tropical Depression Eleven with 30-kt winds, in line with the latest Dvorak Current Intensity numbers from TAFB and SAB. The depression is moving westward, or 280/14 kt, to the south of a large mid-tropospheric high centered over the central Atlantic. This pattern is expected to evolve rather quickly, with a break developing in the ridge over the central Atlantic by 48 hours. This change should allow the depression to begin making more poleward progress, moving west-northwestward from 36 hours until the end of the forecast period. The track models are in good agreement on this scenario, as well as the system's forward speed, and bring the center of the cyclone near or just to the north of the northern Leeward Islands in 4-5 days. This first NHC forecast lies just to the north of the multi-model consensus cluster through day 3, out of respect for the northern-lying ECMWF model, and then is close to HCCA on days 4 and 5. Conventional satellite imagery and Saharan Air Layer analyses suggest that the center of the depression is being shielded from much drier air to its north and west. However, as has been the case for a few days, at least 15 kt of easterly shear has been pushing deep convection to the western side of the circulation. This shear is expected to decrease over the next day or two, which should allow for gradual strengthening to begin by 36 hours, and a peak in the cyclone's intensity should occur in about 3 days. For this period, the NHC intensity forecast is a little above HCCA and the IVCN intensity consensus. After that time, westerly or southwesterly shear is forecast to develop and increase to 20-30 kt by days 4 and 5, which is likely to induce significant weakening. In fact, it's notable that the conditions become hostile enough that the global models are showing the system opening up into a trough near the northern Leeward Islands by day 5, which is a plausible alternate scenario.
