690 WTPZ45 KNHC 200848 TCDEP5 Tropical Storm Elida Discussion Number 23 NWS National Hurricane Center Miami FL EP052026 200 AM PDT Mon Jul 20 2026 Satellite imagery shows convection associated with Elida continues to fade as the cyclone encounters cooler sea surface temperatures, drier air, and increasing southwesterly wind shear. A recent partial ASCAT-C pass indicates the system still has winds of around 42 kt, so the initial intensity is held at 45 kt for this advisory. Gradual weakening is expected through the forecast period as the hostile environmental conditions persist, with the cyclone forecast to degenerate into a remnant low and then eventually dissipate into an open trough in a few days. The latest TAFB satellite intensity estimate was too weak to classify because of the lack of persistent deep convection, suggesting that Elida could degenerate into a post-tropical cyclone sooner than currently forecast if these satellite trends continue. Elida has turned toward the north-northwest and appears to be increasing its forward speed, with the latest motion estimated at 340/11 kt. This north-northwestward then northward motion should continue the next few days as the cyclone moves between a deep-layer trough to its northwest and a ridge centered over the southwestern United States. The NHC track forecast is near the previous, and lies near the corrected consensus HCCA.
