Tropical Storm Elida Discussion Number   6
NWS National Hurricane Center Miami FL       EP092020
300 AM MDT Mon Aug 10 2020

After the earlier burst of deep convection and the development of a 
small 10-nmi-wide low- to mid-level eye noted in passive microwave 
satellite imagery, convection has waned somewhat and the eye feature 
has eroded in the northwestern semicircle due to entrainment of dry 
air, along with some modest northwesterly vertical wind shear. A 
0314Z ASCAT-A overpass revealed peak winds of only 43 kt in the 
northeastern quadrant, along with a radius of maximum winds (RMW) 
of 10-15 nmi. Satellite intensity estimates range from T3.5/55 kt 
from TAFB to T4.0/65 kt from SAB, along with a UW-CIMSS SATCON 
estimate of 53 kt and an ADT estimate of 59 kt. An average of these 
intensity estimates, and allowing for some undersampling by the 
scatterometer instrument due to Elida's small RMW, supports 
maintaining an intensity of 55 kt for this advisory.

The initial motion estimate remains west-northwestward or 300/13 kt. 
Both the forecast track and rationale remain straight-forward and 
basically unchanged from the previous advisory. Elida is expected to 
be steered west-northwestward by a deep layer ridge to the north for 
the next 72 hours or, followed by a westward motion on days 4 and 5 
when Elida will be weakening over much cooler waters and becoming a 
shallower cyclone. The latest NHC track guidance remains tightly 
packed and, thus, the new official forecast is very similar to the 
previous advisory track, and lies near the TVCE and NOAA-HCCA 
consensus track models.

The brief intensity hiatus that Elida is experiencing is expected 
to be short-lived due to the cyclone's small RMW and the vertical 
shear forecast to decrease to less than 10 kt in the 12-36 hour 
time frame. This should allow for Elida to strengthen -- possibly 
even rapidly -- during the next 24 hours, followed by a leveling 
off in the intensity due to the cyclone moving over sub-26C 
sea-surface temperatures (SST).  By 48-60 h, SSTs less than 25C and 
modest southwesterly vertical wind shear will combine to induce 
steady weakening. By 96 h or so, Elida is forecast to degenerate 
into a post-tropical cyclone. The new official intensity forecast is 
a little lower than the previous advisory, but is a little above 
the consensus models IVCN and HCCA.
