Tropical Depression Six-E Discussion Number 2
NWS National Hurricane Center Miami, FL EP062026
2:00 AM Mountain Standard Time, Sunday July 19 2026
The Tropical Depression appears to be slowly becoming better
organized this morning.
However, after the prior advisory, an
ASCAT-B scatterometer pass showed that the circulation remains broad
and is still in the organizing stages.
The latest subjective Dvorak
classification from TAFB was T2.5/35 knots, but the objective intensity
estimates are still in the 25-30 knots range.
A blend of the subjective
and objective estimates supports maintaining the initial intensity
at 30 knots this advisory.
The initial motion continues off to the west-northwest at 290/12 knots.
The depression remains situated to the south of a mid-level ridge
centered over Mexico, though a weakness exists to the northwest,
created by the departing Tropical Storm Elida.
Over the next few
days, the mid-level ridge is expected to build westward, removing
this weakness.
Thus, while TD6-E may gain a bit of latitude in the
24-48 h period, a general west-northwestward motion is expected for
most of the forecast.
The tropical cyclone may even turn a bit
leftward by the end of the forecast period.
The latest the National Hurricane Center track
forecast is just a little north of the prior track forecast, but
remains close to the reliable TVCN and GDMI track aids.
The aforementioned scatterometer data suggests it may take 12-24 h
for the depression's wind field to contract and take advantage of
the environmental conditions.
Other than its short-term structure,
these factors all appear quite favorable for significant
intensification (low shear, ample moisture, very warm sea-surface
temperatures).
Thus, significant intensification is forecast after
the next day or so, especially from 36-60 h where a period of rapid
intensification is explicitly forecast.
There is a negative factor
beyond this time frame.
The current forecast track of the depression
takes the system toward ocean waters churned up by the circulation
of Tropical Storm Elida.
If the tropical cyclone moves over this
cool wake, it could limit the storm's peak intensity beyond 72 h,
with SHIPS guidance showing it close to straddling the 26 C
isotherm.
For now, the the National Hurricane Center intensity forecast still shows a peak
intensity of 95 knots in 72 h, just shy of Major Hurricane (Category 3+) intensity,
with some modest weakening shown in days 4-5.
The the National Hurricane Center intensity
forecast is roughly in between the latest GDMI and HCCA intensity
aids, but is notably higher than the HAFS-A/B guidance this cycle.
