745 WTPZ43 KNHC 211434 TCDEP3 Tropical Storm Celia Discussion Number 20 NWS National Hurricane Center Miami FL EP032022 1000 AM CDT Tue Jun 21 2022 Deep convection has been increasing, but it remains confined to the west of the center of Celia due to about 20 kt of east-northeasterly shear. Even though the cyclone is still asymmetric, it does appear a little better organized than it was several hours ago. The latest Dvorak estimates from TAFB, SAB, and CIMSS at the University of Wisconsin range from 30 to 45 kt, and the initial intensity is nudged up to 35 kt based on that data. This makes Celia a tropical storm once again. Celia is moving just south of due west, or 265 degrees, at 10 kt, and it is currently being steered by a mid-level ridge that is centered over the south-central U.S. A turn to the west-northwest is expected by tonight, and that motion should continue during the next several days as the storm moves within the flow on the southwest side of the ridge. Despite the fairly straightforward steering pattern, there remains a fair amount of spread in the guidance with the HWRF and UKMET models on the southern edge and the ECMWF model on the northern side. The NHC track forecast remains near the middle of the guidance envelope, in best agreement with the various consensus aids. Celia will likely strengthen at a slow pace during the next couple of days as the system remains in moderate to strong shear conditions. The overall environment looks best for Celia late this week and early this weekend, when the shear is expected to decrease and while SSTs beneath the system remain warm, and it will likely become a hurricane during that time. However, later in the weekend, the storm is expected to move over sub 26 C waters, which should end the strengthening trend and induce some weakening. The NHC intensity forecast lies at the low end of the guidance during the next 36-48 hours, but falls near the middle of the envelope beyond that.
