Hello mountain/foothill peeps! Just wanted to announce I’m lurking and here for some vicarious living. Definitely have an eyebrow raised for this event. Lot’s of ifs left to iron out and definitely some bust potential but, the event has me watching. Good luck to all!!!


.

Hmmm….gotta be really close to hurricane Nicole. Maybe 70mph.



.

Missfired into the seasonal thread. Shear vector is pivoting easterly. New strong convection should now wrap the LLC. At any rate, BOOOM!!!

Tropical Storm Julia Discussion Number 5
NWS National Hurricane Center Miami FL AL132022
1100 AM EDT Fri Oct 07 2022

Earlier this morning, a concentrated burst of deep convection with
a high density of lightning developed near the center of the
cyclone while it was over the Guajira Peninsula, and microwave
imagery shows that convective banding has increased somewhat over
the adjacent waters. An Air Force Reserve Hurricane Hunter aircraft
currently investigating the system so far has found maximum 925-mb
flight-level winds of 47 kt and SFMR surface winds of 34 kt, and on
that basis, the depression is upgraded to a 35-kt tropical storm.

Based on the latest aircraft fix, Julia is moving a bit faster
toward the west than expected with an initial motion of 280/16 kt.
A strong east-northeast to west-southwest oriented ridge which
stretches into the southern Gulf of Mexico should keep Julia on a
quick westward path during the next 48 hours. Since the track
guidance has sped up a bit over the past few forecast cycles, the
official forecast now brings Julia to the coast of Nicaragua by
Sunday morning, which is a little sooner than was previously
forecast. After landfall, the track guidance currently indicates
that Julia and its remnants should remain over Central America and
southern Mexico through Tuesday.

Stiff north-northwesterly shear (15-20 kt) is affecting Julia, and
that can be seen in the suppression of the northern edge of the
recent convective burst. Shear diagnostics suggest that this shear
should abate soon, and Julia should commence a steady strengthening
trend during the next two days while it crosses the southwestern
Caribbean Sea. Julia is forecast to become a hurricane by Saturday
evening, and the forecast peak intensity at the time of landfall in
Nicaragua is unchanged from the previous advisory. The official
forecast at that time is a bit above HCCA and the IVCN consensus
aids, but it's still below SHIPS and LGEM guidance. The NHC
forecast shows 72- and 96-hour remnant low points to indicate the
expected track over Central America, but it is highly likely that
the center will have dissipated by those times.


Key Messages:

1. Julia is forecast to strengthen into a hurricane by Saturday
evening while it moves over the southwestern Caribbean Sea, and a
Hurricane Warning is now in effect for San Andres, Providencia, and
Santa Catalina Islands. A Hurricane Watch is also now in effect for
much of the Nicaragua coast. Hurricane-force winds and a dangerous
storm surge are expected in areas where the core of the system
crosses the islands and moves onshore.

2. The risk of flash flooding continues today over portions of the
Guajira Peninsula. The potential for life-threatening flash flooding
and mudslides is expected to spread to portions of Central America
this weekend.

This should be Julia on the next advisory package. Very intense hot tower going up right adjacent to the center that looks to be a formative eastern eyeband. You can make the outline based on GLM lightning data, which is pretty neat. This thing is about to go off.

Special Tropical Weather Outlook to update discussion of the
tropical wave east of the Windward Islands

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:


East of the Windward Islands:
Updated: Visible satellite images and recent satellite-derived
wind data suggest that a broad low-level circulation could be
forming in association with the tropical wave located a few hundred
miles east of the southern Windward Islands. Although the wave
is currently being affected by strong upper-level winds, conditions
could become more conducive for a tropical depression to form while
moving westward at about 15 mph, crossing the Windward Islands
tonight and early Wednesday. Conditions appear to become more
conducive for development later this week when the system reaches
the central and western Caribbean Sea. Regardless of development,
locally heavy rainfall and gusty winds are expected over portions of
the Windward Islands tonight and Wednesday. Interests in the
Windward Islands, the ABC Islands, and the northern coast of
Venezuela should monitor the progress of this system. An Air Force
Reserve Hurricane Hunter aircraft is currently enroute to
investigate this system.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 5 days...medium...60 percent.

Looks like we have a unassigned flight enroute?

Wind field of Ian is absolutely massive

Amazing wind across the Deep South with Ian & pressure gradients.

Tropical Storm Ian Discussion Number 28
NWS National Hurricane Center Miami FL AL092022
1100 AM EDT Thu Sep 29 2022

The center of Ian has emerged into the western Atlantic Ocean to
the north of Cape Canaveral. While satellite images show the
system is becoming a hybrid cyclone, with frontal features outside
of the core of Ian, the winds from multiple sources are notable.
Velocity data from NWS Doppler radar indicate maximum winds of about
70-75 kt at 10,000 ft over land, and sustained winds of about 55 kt
were recorded in the Daytona Beach area earlier this morning. These
data support a higher initial intensity, now 60 kt for this
advisory.

The storm is moving northeastward at about 8 kt. Ian has stubbornly
gone east of the track forecast for the past couple of days and has
moved back over water faster than expected. A mid-level shortwave
trough moving southward across the southern United States should
turn Ian northward overnight and north-northwestward on Saturday.
The official track forecast is shifted to the east, consistent with
the latest consensus guidance.

Ian should move over the Gulf Stream tonight and tomorrow for a
longer period of time than previously anticipated, which should
maintain Ian's central convection. Additionally, an increased
pressure gradient on the northwestern side from a stationary front
near the southeastern US, should provide a boost to the wind speeds
on that side of the storm. We now expect Ian to become a hurricane
again by this evening. As the system approaches South Carolina, Ian
should maintain this intensity, and Hurricane Warnings have been
issued for the entire coast of South Carolina. This scenario is
consistent with the global and regional hurricane model guidance.
It is worth noting that Ian is forecast to have atypical structure
when it nears the southeastern United States, and strong winds will
extend well ahead of the center, even on the northwestern side.

Congrats to the men & women @ the NHC!

Landfall should be any minute, my guess would be North Captiva Island.

Ian looks at his best. Beautiful CDO. Symmetrical, uniform cold cloud tops. Firing on all cylinders. First full Appearance of a cat 5 from a satellite standpoint imo.
