000 WTPZ45 KNHC 162033 TCDEP5 Tropical Storm Elida Discussion Number 9 NWS National Hurricane Center Miami FL EP052026 200 PM PDT Thu Jul 16 2026 Satellite imagery indicates that Elida has become a little better organized since the last advisory, with some convective curvature now seen near the center. However, there is no evidence yet that the storm is developing an eyewall or inner convective core. A recent partial ASCAT overpass showed wind vectors as high as 47 kt northeast of the center. Based on this, possible undersampling issues, and slight increases in the various satellite intensity estimates, the initial intensity is increased to 55 kt. The initial motion is now 280/9 kt. As mentioned in the previous advisory, Elida is forecast to turn northwestward during the next 24 h as it moves through a break in the subtropical ridge caused by a large mid- to upper-level trough west of California. Some of the track guidance shows a more northward motion after 72 h, which could verify if Elida stays vertically stacked as it weakens. However, this is considered unlikely due to the expected shear, and the new forecast track shows a continued northwestward track after the cyclone shears apart. With that being said, the guidance envelope has shifted significantly eastward at 120 h, and the 120 h point is near the left edge of the guidance. If that trend continues, some adjustments may be required in later forecasts. Elida has about 36 h of favorable conditions left before it reaches decreasing sea surface temperatures. The intensity guidance continues to forecast steady intensification during this time, but as before the current structure is a caution flag about how much strengthening might occur. The new intensity forecast shows a peak intensity of 75 kt in 36 h. Beyond that time, cooler waters, increasing vertical shear, and dry air entrainment should cause steady weakening, and Elida is expected to become a remnant low by 120 h. The new intensity forecast follows the overall trend of the intensity guidance.
