MD 1855 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR FAR NORTHERN AZ INTO SOUTHERN/EASTERN UT AND WESTERN CO
Mesoscale Discussion 1855
NWS Storm Prediction Center Norman OK
0108 PM CDT Sun Oct 02 2022
Areas affected...far northern AZ into southern/eastern UT and
western CO
Concerning...Severe potential...Watch unlikely
Valid 021808Z - 022115Z
Probability of Watch Issuance...20 percent
SUMMARY...Sporadic strong thunderstorms may produce hail and strong
gusts through the afternoon from far northern AZ into
southern/eastern UT and western CO.
DISCUSSION...Convection is beginning to develop near the higher
terrain of southern/central UT and northern AZ at midday as lower
elevation temperatures warm into the 60s and 70s. Thunderstorms
should slowly increase in coverage and intensity over the next few
hours. Effective shear magnitudes around 25-35 kt and steepening
low/midlevel lapse rates will support at least periodically
organized cells, with some high-based supercell structures possible.
Meager boundary-layer moisture will limit instability, resulting in
transient stronger cells through the afternoon. Sporadic severe hail
and strong outflow gusts will be possible as convection shifts
east/northeast. Given the transient and isolated nature of any more
intense convection, a watch is not expected at this time.

For storm information specific to your area, please monitor
products issued by your national meteorological service.
DISCUSSION AND OUTLOOK
----------------------
At 1200 PM MDT (1800 UTC), the center of Hurricane Orlene was
located near latitude 19.9 North, longitude 106.9 West. Orlene is
moving toward the north near 8 mph (13 km/h). A turn toward the
north-northeast is expected later today. On the forecast track, the
center of Orlene should pass near or over Las Islas Marias tonight
or Monday morning, and reach the coast of mainland Mexico within the
warning area later on Monday or Monday night.
Maximum sustained winds are near 115 mph (185 km/h) with higher
gusts. Orlene is a category 3 hurricane on the Saffir-Simpson
Hurricane Wind Scale. Weakening is expected during the next day or
so, however Orlene is forecast to be a strong hurricane when it
passes near or over the Islas Marias, and remain a hurricane when it
reaches southwestern Mexico.
Hurricane-force winds extend outward up to 15 miles (30 km) from
the center and tropical-storm-force winds extend outward up to 70
miles (110 km).
The latest minimum central pressure estimated from Air Force
Reserve reconnaissance aircraft data is 972 mb (28.70 inches).
HAZARDS AFFECTING LAND
----------------------
WIND: Hurricane conditions are expected in Las Islas Marias tonight,
with tropical storm conditions beginning later today. Hurricane
conditions are expected in the warning area along the coast of
mainland Mexico late Monday, with tropical storm conditions
beginning early Monday.
Tropical storm conditions are expected to spread northward in the
tropical storm warning area today through early Monday. Hurricane
conditions are possible along the coast of mainland Mexico within
the hurricane watch area by tonight or early Monday. Tropical storm
conditions are possible within the tropical storm watch area today.
RAINFALL: Orlene is expected to produce the following rainfall
across portions of Southwest Mexico through Tuesday:
* Islas Marias: 6 to 10 inches, with local amounts of 14 inches.
* Nayarit and Sinaloa: 3 to 6 inches with local amounts of 10
inches.
* Jalisco and Colima: 1 to 3 inches with local amounts of 5 inches.
These rainfall amounts will likely lead to flash flooding, as well
as possible landslides in areas of rugged terrain.
STORM SURGE: A dangerous storm surge is likely to cause coastal
flooding along the coast of mainland Mexico in the warning area in
regions of onshore winds.
SURF: Large swells generated by Orlene are affecting the west coast
of Mexico and will spread northward to the southern portion of the
Baja California peninsula and the Gulf of California over the next
couple of days. These swells are likely to cause life-threatening
surf and rip current conditions. Please consult products from your
local weather office.

For the eastern North Pacific...east of 140 degrees west longitude:
Active Systems:
The National Hurricane Center is issuing advisories on Hurricane
Orlene, located close to southwestern Mexico.
South-Southwest of the Baja California Peninsula:
Showers and thunderstorms associated with a broad area of low
pressure located several hundred miles south-southwest of the
southern tip of the Baja California peninsula continue to show
signs of organization. Additional development of this system is
possible, and a tropical depression could form during the next
couple of days as it moves slowly northeastward or northward.
Conditions are forecast to become less conducive for development
late this week.
* Formation chance through 48 hours...medium...60 percent.
* Formation chance through 5 days...medium...60 percent.
South of southern Mexico:
A broad area of low pressure has developed several hundred miles
south of the Gulf of Tehuantepec. Environmental conditions are
forecast to be somewhat conducive for gradual development during
the next several days. The low is forecast to move generally
west-northwest during the next couple of days, but could turn
northwestward after midweek.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...20 percent.

1222 PM CDT Sun Oct 02 2022
Valid 031200Z - 041200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Organized severe thunderstorms are not forecast for Monday across
the contiguous United States.
...Synopsis...
A weak mid- to upper-level trough will migrate slowly east across
MT/WY into the Dakotas through Tuesday morning. A surface trough
will extend from the Dakotas southward into the central High Plains
while high pressure influences weather conditions across much of the
central and eastern U.S. Near the surface trough, a narrow plume of
modest moisture (surface dewpoints in the 40s and lower 50s) and
heating will yield MLCAPE around 750 J/kg from SD into NE along the
wind shift, beneath relatively weak midlevel southwesterlies below
30 kt. Scattered convection is likely to form off the Front Range,
producing small hail and locally gusty winds. Given the relatively
dry air mass and weak low-level winds, it appears convection will be
sub severe.
Farther southwest in the Four Corners, primarily diurnal storm
activity will result in widely scattered to scattered storms during
the afternoon to early evening.

...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM UTAH/FOUR
CORNERS TO THE NORTHERN HIGH PLAINS...
...SUMMARY...
Isolated severe hail and wind-producing storms may occur from Utah
northeastward into the northern High Plains this afternoon and early
evening.
...Utah/Four Corners to northern High Plains...
A closed upper low centered over southern Montana will gradually
open and spread slowly eastward, with a southern peripheral belt of
moderately strong westerlies over the Great Basin and central
Rockies. A few areas of showers/thunderstorms are ongoing early
today, but in general, relatively cloud-free skies will allow for
ample early autumn heating and related boundary layer
destabilization this afternoon from southern/eastern Utah into
southern/eastern Wyoming and the nearby High Plains areas including
the Black Hills vicinity.
Destabilizing boundary layer aside, the right-entrance region of a
cyclonically curved mid-level jet will influence thunderstorm
development particularly across southern/eastern Utah. The strength
of mid/high-level west-southwesterly winds (35+ kt effective shear)
could yield some high-based supercells aside from sustained
multicells. Severe hail and severe-caliber winds gusts can be
expected on an isolated basis.
Other storms will also increase over the mountains/interior Wyoming
and move into eastern Wyoming/western South Dakota vicinity later
this afternoon. Meager low-level moisture will limit CAPE and
overall updraft strength. However, moderately strong winds aloft and
steep lapse rates will promote gusty winds and perhaps some hail in
the strongest storms.

Hurricane Orlene Discussion Number 16
NWS National Hurricane Center Miami FL EP162022
900 AM MDT Sun Oct 02 2022
The satellite presentation of Orlene has degraded since early this
morning. It appears that an increase in southwestern shear may
have begun, as the eye has become cloud filled. Subjective satellite
classifications from TAFB and SAB were T5.5 (102 kt), and objective
estimates range from 112 to 120 kt. Based on the degraded
satellite presentation, the initial intensity has been reduced to
110 kt. An Air Force Reserve reconnaissance aircraft is currently
en route to investigate the hurricane, and should provide
additional information on the strength and size of the wind field
early this afternoon.
Orlene has likely peaked in intensity. Although the sea surface
temperatures remain warm along the forecast track, increasing
southwesterly vertical wind shear during the next 24 to 36 hours
is likely to cause the small hurricane to weaken. However, Orlene
is forecast to pass near or over the Islas Marias as a strong
hurricane late tonight or early Monday, and reach the coast of
mainland Mexico has a hurricane by late Monday or Monday night.
After landfall, rapid weakening is expected and the low-level
center should dissipate over the mountainous terrain of
southwestern Mexico in 60-72 hours.
Orlene has continued to move just east of due north or 005/7 kt.
The hurricane is being steered between a mid-level ridge to its
east and a broad trough over northwestern Mexico. These steering
currents should cause Orlene to bend north-northeastward later
today and it should then continue on that general heading until
landfall in southwestern Mexico. The latest NHC track forecast is
slightly west of the previous advisory, and lies close to a blend of
the GFS and ECMWF models (GFEX). This is a little to the right of
the other simple and corrected consensus models. The GFS remains
significantly farther right and faster than the remainder of the
guidance.
Key Messages:
1. Hurricane conditions are expected in the Islas Marias tonight,
with tropical storm conditions beginning today. A Hurricane
Warning is in effect for a portion of west-central mainland Mexico,
where hurricane conditions are expected on Monday with tropical
storm conditions beginning early Monday. Preparations to protect
life and property should be rushed to completion.
2. Heavy rainfall from Orlene is expected to lead to flash flooding,
as well as possible landslides in areas of rugged terrain of
southwestern Mexico into Tuesday.

For storm information specific to your area, please monitor
products issued by your national meteorological service.
DISCUSSION AND OUTLOOK
----------------------
At 1200 PM MDT (1800 UTC), the center of Hurricane Orlene was
located near latitude 17.8 North, longitude 107.0 West. Orlene is
moving toward the north near 5 mph (7 km/h). A north-northeastward
motion at a slightly faster speed is expected to begin by tonight
and continue through early next week. On the forecast track, the
center of Orlene should pass near or over Las Islas Marias Sunday
night or Monday morning and reach the coast of mainland Mexico later
on Monday or Monday night.
Maximum sustained winds are near 75 mph (120 km/h) with higher
gusts. Strengthening is expected through Sunday. After that,
steady weakening is expected to begin by Sunday night. An Air
Force Reserve Hurricane Hunter aircraft is currently enroute to
investigate Orlene.
Orlene remains a small tropical cyclone. Hurricane-force winds
extend outward up to 10 miles (20 km) from the center and
tropical-storm-force winds extend outward up to 45 miles (75 km).
The estimated minimum central pressure is 989 mb (29.21 inches).
HAZARDS AFFECTING LAND
----------------------
WIND: Hurricane conditions are expected in Las Islas Marias Sunday
night, with tropical storm conditions possible by late Sunday.
Tropical storm conditions are expected in the tropical storm warning
area by early Sunday. Hurricane conditions are possible along the
coast of mainland Mexico within the hurricane watch area by Sunday
night into Monday. Tropical storm conditions are possible along the
coast of mainland Mexico within the tropical storm watch area
tonight and Sunday.
RAINFALL: Into Monday evening, Orlene is expected to produce 3 to 5
inches of rainfall, with local amounts of 10 inches, for portions of
Southwest Mexico. These rainfall amounts should lead to flash
flooding, as well as possible landslides in areas of rugged terrain.
STORM SURGE: Coastal flooding is likely along the coast of Mexico
in the warning area in regions of onshore winds.
SURF: Large swells generated by Orlene will affect the coast of
southwestern Mexico, and the extreme southern portion of the Baja
California peninsula through this weekend. These swells are likely
to cause life-threatening surf and rip current conditions. Please
consult products from your local weather office.
