Tropical Storm LINDA (Text)

Tropical Storm Linda Discussion Number  39

1100 AM HST Thu Aug 19 2021
Linda continues to come unhinged. Dry and stable air has wrapped 
almost completely into the cyclone's circulation, as indicated by 
the low-level stratocumulus cloud field that now primarily 
characterizes the system. Linda has now lacked organized deep 
convection for nearly 6 h. A blend of the T- and CI- numbers from 
the latest subjective Dvorak intensity estimates suggest that the 
cyclone's initial intensity has decreased to 45 kt. Cool SSTs of 
24-25 C and dry, stable air should prevent any significant deep 
convection from returning over the next couple of days. Therefore, 
Linda could be declared post-tropical by tonight. The low will reach 
warmer waters in a few days. However, by that time, strong 
southwesterly shear within a dry environment should inhibit 
regeneration of the cyclone, and the low should should open into a 
trough early next week. The latest NHC intensity forecast remains 
near the HCCA and IVCN consensus.

Over the past several hours Linda has moved almost due west with a 
12 h motion of about 275/15 kt. Steered by a low- mid-level ridge to 
its north, a general westward motion is expected  until the system 
dissipates. The latest NHC track forecast is little changed from the 
previous one, and is close to the tightly packed track guidance. 
Linda is crossing into the central Pacific basin, and this will be 
the final NHC advisory on this system. Future information on Linda 
can be found in Forecast/Advisories issued by the Central Pacific 
Hurricane Center beginning at 0300 UTC under AWIPS header HFOTCMCP3 
and WMO header WTPA23 PHFO.
