ZCZC MIATCDEP2 ALL TTAA00 KNHC DDHHMM Hurricane Linda Discussion Number 13 NWS National Hurricane Center Miami FL EP122021 300 AM MDT Fri Aug 13 2021 Over the past couple of hours, satellite images show the convection becoming more symmetrical around warming cloud tops over Linda's center, indicating a better-defined eye may be forming. The latest Dvorak intensity estimates ranged from 65 to 82 kt, and based on the recent satellite trends, the higher end of these estimates are favored for an initial intensity of 80 kt. A recent ASCAT overpass was able to provide useful information regarding the cyclone's wind radii, with winds of tropical storm force extending up to 150 n mi to the south of its center. Given the improving structure of the cyclone, Linda is expected to strengthen quickly over the next day or so, while the system is forecast to remain in an environment of decreasing vertical wind shear and over warm waters. By 48 h, decreasing SSTs and increasingly unfavorable thermodynamic conditions should cause the cyclone to begin weakening. The latest NHC intensity forecast is little changed from the previous one, and lies between the IVCN consensus and the HFIP corrected consensus HCCA. Linda is moving toward the west-northwest at 11 kt along the periphery of a mid-level ridge to its north and northeast. This ridge is forecast to build westward with time, and eventually build to the northwest of the cyclone as well, forcing it to the west in a couple of days and then perhaps west-southwest later in the forecast period. The track guidance is in very good agreement on this scenario and only slight adjustments were made to the previous NHC track forecast. This prediction lies near the various consensus model tracks.
