Post-Tropical Cyclone One-E Forecast Discussion Number 6
2020-04-26 22:35:34| National Hurricane Center (East Pacific)
Issued at 200 PM PDT Sun Apr 26 2020 000 WTPZ41 KNHC 262035 TCDEP1 Post-Tropical Cyclone One-E Discussion Number 6 NWS National Hurricane Center Miami FL EP012020 200 PM PDT Sun Apr 26 2020 The cyclone has lacked significant organized deep convection for at least 10 hours, and the system is moving into increasingly more stable air and over sub-25C deg C SSTs. Therefore, the depression has been downgraded to a post-tropical remnant low. The initial intensity is 25 kt is based on several 23-25 kt wind vectors located n-e of the low-level center in a 1718 UTC ASCAT-A overpass. Although the system may still produce some sporadic convection late tonight during the convective maximum period, dry and stable air along with strong westerly shear will likely prevent any appreciable convection from persisting over the next day or so. This should cause the remnant low to weaken and then open up into a trough in 36-48 hours. The initial motion remains 305/08 kt. A substantial low- to mid-level ridge to the north of the cyclone is expected to gradually nudge the shallow low toward the west-northwest later this afternoon, followed by a westward motion tonight, with that motion continuing until the system dissipates Monday night. The new NHC track forecast is essentially just an update of the previous advisory track. This is the last advisory issued by the National Hurricane Center on this system. For additional information on the remnant low, please see High Seas Forecasts issued by the National Weather Service, under AWIPS header NFDHSFEPI, WMO header FZPN02 KWBC, and on the web at ocean.weather.gov/shtml/NFDHSFEPI.php .

Issued at 200 PM PDT Sun Apr 26 2020 000 WTPZ31 KNHC 262034 TCPEP1 BULLETIN Post-Tropical Cyclone One-E Advisory Number 6 NWS National Hurricane Center Miami FL EP012020 200 PM PDT Sun Apr 26 2020 ...DEPRESSION DEGENERATES INTO A REMNANT LOW PRESSURE SYSTEM... ...THIS IS THE LAST ADVISORY... SUMMARY OF 200 PM PDT...2100 UTC...INFORMATION ---------------------------------------------- LOCATION...16.2N 119.4W ABOUT 770 MI...1240 KM SW OF THE SOUTHERN TIP OF BAJA CALIFORNIA MAXIMUM SUSTAINED WINDS...30 MPH...45 KM/H PRESENT MOVEMENT...NW OR 305 DEGREES AT 9 MPH...15 KM/H MINIMUM CENTRAL PRESSURE...1007 MB...29.74 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 Post-Tropical Cyclone One-E was located near latitude 16.2 North, longitude 119.4 West. The post-tropical cyclone is moving toward the northwest near 9 mph (15 km/h). A motion toward the west-northwest is expected by late afternoon, followed by a turn toward the west tonight. Maximum sustained winds have decreased near 30 mph (45 km/h) with higher gusts. Additional weakening is forecast during the next 48 hours, and the system is expected to dissipate by Monday tonight. The estimated minimum central pressure is 1007 mb (29.74 inches). HAZARDS AFFECTING LAND ---------------------- None. NEXT ADVISORY ------------- This is the last public advisory issued by the National Hurricane Center on this system.

Tropical Depression One-E Forecast Discussion Number 5
2020-04-26 16:38:52| National Hurricane Center (East Pacific)
Issued at 800 AM PDT Sun Apr 26 2020 000 WTPZ41 KNHC 261438 TCDEP1 Tropical Depression One-E Discussion Number 5 NWS National Hurricane Center Miami FL EP012020 800 AM PDT Sun Apr 26 2020 Deep convection has been waning quickly in the southeastern quadrant since the previous advisory, and the system barely met Dvorak criteria for identifying it as a tropical cyclone at 1200 UTC. Given that the 0446 UTC ASCAT-A overpass mentioned in the previous discussion revealed a fairly sizable area of 28-30 kt winds in the northeastern quadrant, there might be one or two 30-kt vectors remaining despite the recent decline in the convective pattern, and thus the intensity has been held at 30 kt for this advisory. The initial motion remains northwestward, or 305/08 kt. A strong subtropical ridge to the north of the depression is expected to gradually turn the cyclone toward the west-northwest later today and then westward by tonight, with a westward motion being maintained thereafter until the system dissipates by late Monday. The new NHC track forecast is essentially just an extension of the previous advisory track, and lies close to the tightly packed consensus track models Deep-layer dry air and cooler sea-surface temperatures, combined with strong westerly shear of 25-30 kt, should continue to erode what little bit of convection remains, causing the system to rapidly degenerate into a remnant low by this afternoon or evening. The low is then expected to dissipate by Monday night. The new intensity forecast is similar to the previous advisory, and closely follows the intensity consensus models IVCN and HCCA.
