Enrique looks stationary to me. It's going to be upwelling cooler water soon if it doesn't get moving.

00z HWRF peaks it near 85kts/100mph.

00z HMON makes this a borderline major hurricane.

Enrique's small eye is starting to peek through as wrapping convective bursts drive core subsidence. Does Enrique have the time to properly clear out its eye before the environment catches up? The HWRF sure seems to think so.

Latest AMSR2 pass shows concentric eyewalls... Looks like it was attempting an ERC 2 hours ago:
Image

Excellent inner structure regardless.
Image

Considering that ERC's mainly happen with Cat.3+ canes while also considering dry air is probably playing a role here, suggests this was/is at least a Cat.2 hurricane in the past 6 hours.

06z HWRF peaks it @ 966mb/90kts. But its IR presentation resembles a mature major hurricane.

This storm can not handle the dry air intrusions an ERC would bring whatsoever. With that said, that’s not an ERC and more likely a dry air intrusion.

Hurricane Enrique Discussion Number 9
NWS National Hurricane Center Miami FL EP052021
300 AM MDT Sun Jun 27 2021

The central dense overcast of the hurricane has not expanded much
over the past several hours, and the eye is not apparent on
geostationary satellite images. However, Enrique has well-defined
convective banding features over most of its circulation. Taking a
blend of the latest Dvorak intensity estimates from TAFB and SAB
gives a current intensity estimate of 80 kt. A little more
strengthening could occur today, as reflected in the official
forecast. In 24 to 48 hours, cooler sea surface temperatures and
decreasing oceanic heat content should cause a weakening trend to
commence. Later in the forecast period, the cyclone should be
entraining a drier and more stable air mass near the southern Baja
California peninsula, which should also contribute to the
weakening process. The official intensity forecast is similar to
the previous one and close to the HFIP Corrected Consensus and FSU
Superensemble predictions.

Enrique has moved quite slowly overnight and the initial motion
estimate is north-northwestward, or 330/3 kt. Steering currents
are expected to remain rather weak over the next few days. The
system is expected to move on a north-northwestward to
northwestward heading, in the general direction of a weak mid-level
trough over extreme northwestern Mexico, for the next 2-3 days.
Later in the forecast period, the weakening cyclone's track should
gradually bend to the left under the influence of the
lower-tropospheric environmental flow. The official track forecast
is a blend of the latest GFS and ECMWF solutions, and not too
different from the previous NHC track.


Key Messages:

1. The outer rainbands of Enrique are likely to produce heavy rains
across a portion of southwestern Mexico during the next couple
of days, which would likely cause life-threatening flash flooding
and mudslides.

2. Tropical-storm-force winds are expected to continue across
portions of southwestern Mexico through early Monday. Although the
core of Enrique is still forecast to remain just offshore, any
deviation to the right of the forecast track or expansion of the
wind field could bring even stronger winds onshore over a portion
of the southwestern coast of Mexico. Therefore, a Hurricane Watch
is in effect for a portion of that area.

3. Swells generated by Enrique are expected to affect the
southwestern coast of Mexico during the next few days. These swells
could cause life-threatening surf and rip currents.

Its been having dry air intrusions for the past 24 hours. Its MW presentation has consistently resembled this SSMIS F-18 pass taken 12 hours ago:
Image

This recent AMSR2 pass, is differently clearly depicting a ERC. Two seperated convectively deep eyewalls and a moat which is very similar to MW imagery found in ERC case studies.

DISCUSSION AND OUTLOOK
----------------------
At 600 AM MDT (1200 UTC), the center of Hurricane Enrique was
located near latitude 17.9 North, longitude 105.9 West. Enrique is
moving toward the north near 4 mph (6 km/h). A north-northwest to
northwestward motion is expected during the next couple of days. On
the forecast track, the center of Enrique is expected to pass near
or just offshore of the southwestern coast of Mexico late today
through Monday.

Maximum sustained winds are near 90 mph (150 km/h) with higher
gusts. Some additional slight strengthening is possible today.
Enrique is expected to begin to gradually weaken over cooler waters
on Monday and Tuesday.

Hurricane-force winds extend outward up to 25 miles (35 km) from
the center and tropical-storm-force winds extend outward up to 125
miles (205 km).

The estimated minimum central pressure is 977 mb (28.85 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for Hurricane Enrique can be found in the Tropical
Cyclone Discussion under AWIPS header MIATCDEP5, WMO header WTPZ45
KNHC, and on the web at
www.hurricanes.gov/graphics_ep5.shtml?key_messages.

WIND: Tropical storm conditions are occuring in portions of the
warning area and will continue to spread northwestward within the
warning area through tonight. Hurricane conditions are possible by
tonight in the Hurricane Watch area. Tropical storm conditions are
possible in the Tropical Storm Watch area today and Monday.

RAINFALL: Through Tuesday, The eastern outer bands of Enrique are
expected to produce total rainfall amounts of 6 to 12 inches with
isolated maximum amounts of 18 inches over Colima and coastal
sections of Jalisco, Michoacan, and northern Guerrero in southwest
Mexico. These amounts would likely produce life-threatening flash
flooding and mudslides over portions of southwestern Mexico.

SURF: Swells generated by Enrique will affect the southwestern
coast of Mexico during the next few days. These swells are likely
to cause life-threatening surf and rip current conditions. Please
consult products from your local weather office.

Doesn't look like it's going to get much stronger than it is now, but at least it became a hurricane. Hopefully Mexico doesn't get any major impacts from this.

Hurricane Enrique Discussion Number 10
NWS National Hurricane Center Miami FL EP052021
1000 AM CDT Sun Jun 27 2021

Enrique has been holding its own over the past several hours, with
some warming of the cloud tops over the estimated center, suggesting
that an eye is attempting to form. The northern portion of the core
appears to be entraining some dry air, which is likely due to
down-sloping from the offshore flow over the mountainous terrain of
Mexico. Otherwise, the core of the hurricane appears well intact,
and the latest Dvorak intensity estimate T-number from TAFB
indicates that the initial intensity remains 80 kt for this
advisory.

Enrique has been wobbling on a nearly due north trajectory for the
past 12 h or so, while the forward motion has appeared to increase
to about 5 kt. There is little change to the forecast track
reasoning. Embedded in generally weak steering flow, Enrique is
forecast to move toward a mid-level trough over northwestern Mexico.
This trough is expected to gradually fill in over the next day or
so, causing the system to turn to the north-northwest. By late
Monday and Tuesday, the weakening cyclone should turn northwestward
as it becomes steered by the lower-tropospheric environmental flow.
The latest NHC track forecast is very near the previous one, and is
close to the TVCE consensus.

Overall, the environment surrounding Enrique is favorable for
strengthening in the near term. On Monday, the hurricane is forecast
to begin moving over waters of decreasing oceanic heat content. Due
to the fairly slow motion of the cyclone over these waters,
upwelling should bring cooler waters to the surface. This would
induce a gradual weakening trend beginning sometime tomorrow. By
Tuesday, the cyclone is expected to begin moving over much cooler
waters and into a drier and stable atmospheric environment, which
will hasten the pace of weakening. Most of the guidance shows
Enrique becoming a remnant low very near the time it reaches the
southern Baja California peninsula, with the low dissipating a short
time thereafter. Other than indicating a little faster transition to
a remnant low and dissipation, the official intensity forecast is
very similar to the previous one, near the high end of the guidance
through 36 h, and then a blend of the SHIPS/LGEM models and the
intensity consensus after 36 h.


Key Messages:

1. The outer rainbands of Enrique are likely to produce heavy rains
across a portion of southwestern Mexico during the next couple of
days, which would likely cause life-threatening flash flooding and
mudslides.

2. Tropical-storm-force winds are expected to continue across
portions of southwestern Mexico through early Monday. Although the
core of Enrique is still forecast to remain just offshore, any
deviation to the right of the forecast track or expansion of the
wind field could bring even stronger winds onshore over a portion of
the southwestern coast of Mexico. Therefore, a Hurricane Watch
remains in effect for a portion of that area.

3. Swells generated by Enrique are expected to affect the
southwestern coast of Mexico during the next few days. These swells
could cause life-threatening surf and rip currents.

i hope it remembers to turn northwest.
glad i have a trash pump to use for emptying my dinghy. some of these have been 2 pump storms, when water gets 10 inches deep each time.
we so need the water, but not the blowdry.
the models i have been able to see, ecmwf and gfs, our normally most accurate for us, show it breaking up by the prison islands and plundering cabo san lucas with a weak and dying attempt, with some weather sent up sea on baja side to terrorize anchored sailboat cruisers.
if this lil storm is well behaved i may sit out in cockpit to watch it blow by. if it is not well behaved i will be a busy sailorette or inside reassuring cats they wont die. .
