Still a tropical storm. I must say, Douglas has done MUCH better than Elida.

Re: EPAC: DOUGLAS - Tropical Storm
TROPICAL STORM DOUGLAS DISCUSSION NUMBER 19
NWS NATIONAL HURRICANE CENTER MIAMI FL EP042014
200 AM PDT THU JUL 03 2014
After an earlier burst of convection in the northern semicircle,
thunderstorm activity has been gradually waning over the past few
hours with cloud tops warming during the normal convective maximum
period. However, TRMM and AMSU microwave satellite data indicate
that Douglas has maintained a tight low-level circulation,
including a shallow eye-like feature, so the initial intensity is
being maintained at 35 kt, which is consistent with satellite
estimates of 35 kt from TAFB and 34 kt from the UW-CIMSS ADT.
Douglas is moving slowly northwestward, or 315/03 kt. There is no
significant change to the previous forecast track or reasoning.
Douglas is expected to steadily weaken and gradually become a more
shallow vortex that will be steered toward the west-northwest or
west by low-level trade wind flow on the south side of the Pacific
subtropical ridge. The official NHC forecast track is basically
just an update of the previous advisory track and lies close to but
just south of the consensus model TVCE.
Douglas will gradually weaken throughout the forecast period as the
cyclone ingests cooler and more stable air, and also moves over
sub-24C sea-surface temperatures by 24 hours. Douglas should become
a depression later today, possibly even this morning, and degenerate
further into a remnant low by Friday. The NHC intensity forecast is
consistent with most of the available intensity guidance.

Re: EPAC: DOUGLAS - Tropical Storm
TROPICAL STORM DOUGLAS DISCUSSION NUMBER 20
NWS NATIONAL HURRICANE CENTER MIAMI FL EP042014
800 AM PDT THU JUL 03 2014
Douglas is still producing a small but compact area of deep
convection. Satellite intensity estimates are straddling the
tropical storm threshold, so I am opting to maintain Douglas as a
tropical storm until we get a few visible satellite images and
possibly an ASCAT pass later today. Regardless, cold water and dry,
stable air should cause Douglas to weaken to a tropical depression
soon and degenerate into a remnant low in about 24 hours.
Dissipation is forecast by day 5.
The initial motion is still slow...320/2 kt. A mid-level high
centered just northeast of Hawaii continues to impede Douglas from
making much westward progress, but this feature is expected to shift
westward during the next 48 hours. At the same time, mid-level
ridging will build over the western United States. Douglas is
therefore expected to turn west-northwestward and accelerate after
36 hours. The updated NHC track forecast has been shifted to the
right a bit and lies fairly close to the model consensus TVCE.

Re: EPAC: DOUGLAS - Tropical Storm
TROPICAL DEPRESSION DOUGLAS DISCUSSION NUMBER 21
NWS NATIONAL HURRICANE CENTER MIAMI FL EP042014
200 PM PDT THU JUL 03 2014
Douglas's low-level center is located just to the west of a small
area of deep convection. Satellite intensity estimates have
decreased a bit since this morning, and a blend of the Final-T and
CI numbers from TAFB, SAB, and the objective ADT support
downgrading Douglas to a 30-kt depression. Continued weakening is
forecast while the depression moves over increasingly cooler
water and into a drier, more stable environment. Douglas is
forecast to degenerate into a remnant low by 24 hours, but it
could become one earlier if the deep convection diminishes soon.
Dissipation is still expected by day 5.
Douglas continues to creep northwestward with an initial motion of
315/2 kt. Low- to mid-level ridging is expected to build over the
western United States during the next 48 hours, which should cause
the remnant low to turn west-northwestward and accelerate by days 3
and 4. The model guidance is in good agreement, and no significant
changes were required to the official NHC track forecast in this
advisory.

The center of Douglas is partially exposed to the west of a small
area of deep convection. Satellite intensity estimates are about
the same as earlier, so 30 kt is kept as the initial wind speed.
Douglas should gradually lose strength over the next few days while
it moves over cold water within a more stable environment. The
latest NHC intensity prediction is about the same as the previous
one. Douglas will likely become a remnant low on Friday while it
traverses sub-24C waters. The low should dissipate in about 4 days
according to the global model guidance.
The depression is moving a little faster toward the northwest at
about 4 kt. Low- to mid-level ridging is expected to build somewhat
over the western United States during the next 48 hours, which
should cause Douglas or its remnants to speed up a little bit.
Model guidance is virtually unchanged from 6 hours ago, so the
latest NHC track forecast is basically an update of the previous
one.

Re: EPAC: DOUGLAS - Tropical Depression
TROPICAL STORM DOUGLAS DISCUSSION NUMBER 23

200 AM PDT FRI JUL 04 2014
Douglas consists of a tight swirl of low clouds accompanied by
a small curved band of deep convection to the east of the center.
NHC had estimated that the peak winds were 30 knots, but a
recent ASCAT-B pass shows numerous 35-kt wind vectors associated
with the circulation of Douglas. The initial intensity has thus been
adjusted to 35 knots. This does not mean that Douglas has
restrengthened. Instead, the lack of data earlier led us to a lower
wind estimate. Nevertheless, the cyclone is over 24 degree Celsius
water and weakening to a remnant low in a day or so is still
anticipated.
The initial motion is toward the northwest or 315 degrees at 5
knots. This general motion is expected to continue during the next
24 to 48 hours with a gradual turn to west as the subtropical ridge
to the north of the cyclone builds westward.

Re: EPAC: DOUGLAS - Tropical Storm
TROPICAL STORM DOUGLAS DISCUSSION NUMBER 24
NWS NATIONAL HURRICANE CENTER MIAMI FL EP042014
800 AM PDT FRI JUL 04 2014
Douglas may well have weakened to a tropical depression since the
time of an overnight ASCAT pass, given that deep convection
associated with the storm has shrunk in size and become displaced
well southeast of the center. However, we'll hold Douglas as a
tropical storm a while longer pending a more definitive indication
of weakening. With some northwesterly shear and a forecast track
that takes Douglas over even cooler waters, the cyclone should
degenerate into a remnant low soon. The NHC intensity forecast is
the same as the previous one and shows remnant low status within 24
hours.
The initial motion is 310/05. A building low- to mid-level ridge
over the western United States should steer the storm northwestward
and then west-northwestward at a slightly faster forward speed until
dissipation in about 72 hours. This is in agreement with the latest
model guidance and just a bit slower than the multi-model consensus.

Douglas may well have weakened to a tropical depression since the
time of an overnight ASCAT pass, given that deep convection
associated with the storm has shrunk in size and become displaced
well southeast of the center. However, we'll hold Douglas as a
tropical storm a while longer pending a more definitive indication
of weakening. With some northwesterly shear and a forecast track
that takes Douglas over even cooler waters, the cyclone should
degenerate into a remnant low soon. The NHC intensity forecast is
the same as the previous one and shows remnant low status within 24
hours.
The initial motion is 310/05. A building low- to mid-level ridge
over the western United States should steer the storm northwestward
and then west-northwestward at a slightly faster forward speed until
dissipation in about 72 hours. This is in agreement with the latest
model guidance and just a bit slower than the multi-model consensus.

TROPICAL STORM DOUGLAS DISCUSSION NUMBER 25
NWS NATIONAL HURRICANE CENTER MIAMI FL EP042014
200 PM PDT FRI JUL 04 2014
Even though Douglas has been devoid of deep convection for about six
hours, a 1716 UTC ASCAT overpass indicated a patch of wind near
tropical-storm strength north-northwest of the center. Therefore,
the initial intensity is held at 35 kt for this advisory. With the
cyclone now over 23-degree C water and embedded in a dry and very
stable air mass, it seems unlikely that any deep convection would
re-develop. Douglas is forecast to degenerate into a remnant low
within 12 hours, and the circulation of the decaying cyclone should
gradually spin down during the next couple of days.
The initial motion estimate is 305/05, a little to the left than
before. A low-level ridge of high pressure west of the southern
tip of the Baja California peninsula should keep the cyclone moving
west-northwestward or northwestward until dissipation in about 3
days.

I like it too. But I think this will be its last advisory as a tropical storm, because convection is really weak right now and waters are very cold.
