Tropical Storm Dalila Discussion Number   5
NWS National Hurricane Center Miami FL       EP052019
200 AM PDT Tue Jul 23 2019

Deep convection has become stronger and closer to the center of the
cyclone during the past several hours.  While the circulation is
still elongated, it has become better defined, with the latest ASCAT
pass at 0440 UTC showing 30-35 kt winds in the southern quadrant.
Since TAFB, ADT and SATCON have the current intensity as a tropical
storm, plus the recent increase in organization, the current wind
speed has been set to 35 kt.

Dalila is probably near peak intensity. Since SSTs drop off later
today, along with a continuation of moderate northerly shear,
weakening should begin on Wednesday.  In a couple of days, SSTs near
24C, dry air aloft, and a more stable atmosphere should contribute
to Dalila losing deep convection, thus becoming a remnant low. This
is the solution provided by much of the guidance, and the latest NHC
intensity prediction is close to the previous one.

The cyclone has been moving erratically at 330/6 due to the center
trying to reform near the strong convection to the south.  A
mid-level ridge over the southwestern United States should provide
similar steering during the next day or so, causing a motion
generally toward the northwest by Wednesday.  As Dalila weakens, it
will likely turn more to the west-northwest on Thursday within the
low-level flow.  Similar to the past few cycles, model guidance is
continuing to shift westward, and the official forecast follows that
trend, not terribly far from the eastern Pacific track consensus
model TVCE.

Tropical Depression Five-E Discussion Number   1
NWS National Hurricane Center Miami FL       EP052019
200 AM PDT Mon Jul 22 2019

The area of disturbed weather and low pressure system located about
600 nmi southwest of Baja California Sur that the NHC has been
monitoring for the past several days has finally developed a
sufficient inner-core wind field and enough organized deep
convection to be classified as a tropical cyclone. The initial
intensity is set at 30 kt based on two ASCAT passes between
0430-0530Z that showed 30-31 kt wind vectors in the western
quadrant, which corresponds well with the latest TAFB Dvorak
satellite intensity estimate of T2.0/30 kt from TAFB.

The initial motion estimate is an uncertain 360/08 kt due to the
lack of a well-defined center until recently. However, the NHC model
guidance is in surprisingly good agreement on the cyclone moving
northward for the next 36-48 hours around the eastern periphery of a
broad mid-level low/trough located to the west of the depression. By
72 h and continuing through 120 h, the cyclone is forecast to move
northwestward as a weakening remnant low pressure system. The NHC
forecast track lies close to a blend of the various consensus
models, and is about midway between the GFS and ECMWF model
solutions that bound on the eastern and western fringes,
respectively, of the track guidance envelope.

Modest north to northeasterly vertical wind shear and occasional
intrusions of dry air are expected to hinder development and
strengthening for the next 48 hours or so. By late on day 2 and
especially by day 3, the cyclone will be moving over sub-26 deg C
sea-surface temperatures, which will induce at least steady
weakening despite decreasing vertical wind shear conditions during
that time. The official intensity forecast is similar to but
slightly higher higher than the IVCN and HCCA intensity consensus
models, with the latter guidance calling for no strengthening.
