The last few runs of the GFS and AI-assisted GFS models have been hinting at tropical development in the Atlantic MDR over the next ~5 days. The GFS stands alone - no other global/synoptic model solutions show any meaningful activity.

Some additional information - in case you're new to this sub (or just modeling in general)...

The Global Forecasting System (operated under the NOAA/NWS umbrella, i.e., "GFS" or the "American Model") is one of several global (i.e., synoptic) scale models used to aid official forecasts. Other models include the European model ("ECMWF"), the Canadian Model ("GEM" or "CMC"), and German Model ("ICON"), etc.

These are examples of synoptic scale models, which focus on large-scale atmospheric patterns. To put it simply, computers take the latest observational data and run them through complex algorithms that mock the laws of physics to determine plausible outcomes.

There also AI-based and AI-assisted models, which compare the latest observations with past observations over many years, to identify meteorological trends. For example, Google has developed its own AI-based line of models (e.g., "WeatherNext"). AI-assisted models use a blend of physics and historical trends.

The GFS model is particularly quirky and known to enter feedback loops in the long-term, resulting in a strong bias to produce monster low pressure systems. You'll see this in long-term modeling in the tropics during summer and also in the mid-latitudes during winter. It's one of the reasons this sub has strict posting requirements when it comes to posting modeling beyond 120 hours (5 days).

So why am I posting this?

  • First, even a broken clock is right once in awhile. Last year, the GFS model was the first synoptic model to identify the disturbance that would become Hurricane Melissa.
  • The 06z runs are not "one-offs." This is now a trend with several recent runs of GFS-based models producing at least a tropical depression in the MDR.
  • The open question of the Madden-Julian Oscillation ("MJO"). This is a global scale weather pattern that can be highly influential on tropical development around the world.
    • When the MJO is in Phases 7, 8 and 1, conditions in the Atlantic become more favorable for tropical development. If the MJO is in any other phase, or is weak/neutral, then conditions will likely remain unfavorable.
    • GFS and ECMWF modeling of the MJO over the next 15 days are very different right now. (See Slide 9). The GFS has been trending toward an active MJO in Phase 7, albeit not until September.... but that could be linked to how its modeling in the Atlantic.
    • Notably, the latest GFS ensemble modeling of the MJO looks more like the ECWMF and other models, taking the MJO into a weak or neutral phase.
u/BostonSucksatHockey — 2 days ago

Both of those Atlantic disturbances: gone

There were a couple of disturbances over the past few days in the central and eastern Atlantic but both have dissipated. Coming into peak season soon and it's still quiet (knocks on wood).

Can Earthquake Sensors Detect Hurricanes?

Can scientists use earthquake sensors to detect hurricanes? 

​A new study from Stanford University found that seismometers, normally used to measure earthquake-related ground motion, can also detect hurricanes. Researchers looked at Hurricane Isaac from 2012 and found that seismometers could detect when the storm made landfall as well as subtle changes in atmospheric pressure. These sensors could potentially track how hurricanes evolve beyond the limitations of radar and flight missions during storms.

SITUATION OVERVIEW

------------------

Hurricane Lala will bring damaging winds, heavy rainfall leading to

flash flooding, and dangerously high surf to portions of the state

this weekend. Impacts have already begun over portions of the Big

Island of Hawaii, with impacts expected to spread westward across

Maui County this afternoon, Oahu this afternoon into the evening,

and Kauai tonight. Lala is expected to pass near or make landfall

over the southern end of the Big Island of Hawaii this afternoon and

pass just south of the rest of the island chain through Sunday.

Damaging winds and heavy rainfall are expected across the entire

state this weekend, with the Big Island of Hawaii likely seeing the

greatest impacts. Do not focus on the exact forecast track or

intensity of Lala at this time, and be prepared for changes in

future forecasts.

Damaging tropical storm force winds will increase across parts of

the Big Island of Hawaii and Maui County, with hurricane force winds

possible as Lala moves near or over the Big Island today. Damaging

winds are expected to spread westward to Oahu and Kauai later this

evening and into Sunday. It is very important to note that the

mountainous terrain of the islands will likely produce localized

areas of highly enhanced and damaging winds, even well away from the

tropical cyclone center.

Flooding rain will continue to increase on the Big Island of Hawaii

throughout the day today as Lala approaches. The threat for flooding

will also increase over Maui County today and spread to the rest of

the state this evening and Sunday. Heavy rainfall could persist into

Monday for some areas, mainly over the western end of the island

chain. Lala is expected to produce rainfall totals of 10 to 20

inches, with locally higher amounts possibly up to 25 inches, across

windward Big Island. Rainfall totals of 8 to 12 inches are possible

on windward Maui and up to 8 inches of rainfall could occur across

the remainder of the island chain. While the highest rainfall

amounts will be focused over windward areas, leeward areas will also

have a significant flood risk.

Large swells generated by Lala will peak today into tonight and

produce dangerous surf along exposed east and southeast shores of

all islands. Very large and extremely rough seas impacting the

exposed southeast and east shores of the Big Island are expected to

expand to Maui later today, and then Oahu and Kauai by late tonight.

Damaging surf, significant beach erosion, and overwash across

vulnerable coastal infrastructure is possible.

POTENTIAL IMPACTS

-----------------

* WIND:

Potential impacts from the main wind event are now unfolding across

the Big Island of Hawaii. Remain well sheltered from life-threatening

wind having possible extensive impacts. If realized, these impacts

include:

- Considerable roof damage to sturdy buildings, with some having

window, door, and garage door failures leading to structural

damage. Mobile homes severely damaged, with some destroyed.

Damage accentuated by airborne projectiles. Locations may be

uninhabitable for weeks.

- Many large trees snapped or uprooted along with fences and

roadway signs blown over.

- Some roads impassable from large debris, and more within urban

or heavily wooded places. Several bridges, causeways, and

access routes impassable.

- Large areas with power and communications outages.

Potential impacts from the main wind event are also now unfolding

across the rest of the state. Remain well sheltered from dangerous

wind having possible limited to significant impacts.

* SURGE:

Potential impacts from the main surge event are now unfolding across

the Big Island of Hawaii. Remain well away from locally hazardous

surge having possible limited impacts. If realized, these impacts

include:

- Localized inundation with storm surge flooding mainly along

immediate shorelines and in low-lying spots, or in areas

farther inland near where higher surge waters move ashore.

- Sections of near-shore roads and parking lots become overspread.

- Moderate beach erosion. Heavy surf also breaching dunes, mainly

in usually vulnerable locations. Strong rip currents.

- Minor to locally moderate damage to marinas, docks, boardwalks,

and piers. A few small craft broken away from moorings.

* FLOODING RAIN:

Potential impacts from the flooding rain are still unfolding across

the Big Island of Hawaii. Remain well guarded against life-threatening

flood waters having possible extensive impacts. If realized, these

impacts include:

- Major rainfall flooding may prompt many evacuations and rescues.

- Rivers and tributaries may rapidly overflow their banks in

multiple places. Small streams, creeks, canals, arroyos, and

ditches may become dangerous rivers. In mountain areas,

destructive runoff may run quickly down valleys while

increasing susceptibility to rockslides and mudslides. Flood

control systems and barriers may become stressed.

- Flood waters can enter many structures within multiple

communities, some structures becoming uninhabitable or washed

away. Many places where flood waters may cover escape routes.

Streets and parking lots become rivers of moving water with

underpasses submerged. Many road and bridge closures with some weakened or washed out.

Potential impacts from the flooding rain are still unfolding across

the rest of the state. Remain well guarded against dangerous flood

waters having possible limited to significant impacts.

* TORNADOES:

Potential impacts from tornadoes are still unfolding across the

Hawaiian islands. Remain well braced against a tornado event having

possible limited impacts. If realized, these impacts include:

- The occurrence of isolated tornadoes can hinder the execution

of emergency plans during tropical events.

- A few places may experience tornado damage, along with power

and communications disruptions.

- Locations could realize roofs peeled off buildings, chimneys

toppled, mobile homes pushed off foundations or overturned,

large tree tops and branches snapped off, shallow-rooted trees

knocked over, moving vehicles blown off roads, and small boats

pulled from moorings.

PRECAUTIONARY/PREPAREDNESS ACTIONS

----------------------------------

* EVACUATIONS:

Follow the advice of local officials

* OTHER PREPAREDNESS INFORMATION:

During the peak of the storm be ready to move quickly. Keep your

shoes on and rain gear handy. Boots and athletic shoes offer the best

foot protection if you become unexpectedly exposed to the weather.

Keep your cell phone charged and in power-saving mode. If you lose

power, use it sparingly and mainly for personal emergencies and

check-ins.

Do not be a thrill seeker or risk your life for senseless photos or

videos.

Quickly move to the safest place within your shelter if it begins to

fail, preferably an interior room on the lowest floor as long as

flooding is not a concern.

If you are prone to flooding or in an area under a storm surge watch

or warning, be prepared for the possibility of a quick and dramatic

rise in water levels.

DISCUSSION AND OUTLOOK

----------------------

At 200 AM HST (1200 UTC), the center of Tropical Storm Lala was

located near latitude 16.6 North, longitude 149.3 West. Lala is

moving toward the west-northwest near 10 mph (17 km/h). This

general motion is expected to continue, taking the core of Lala

near the Big Island of Hawaii on Saturday and then south of the

smaller islands on Sunday.

Maximum sustained winds remain near 60 mph (95 km/h) with higher

gusts. Steady strengthening is forecast, and Lala is expected to

become a hurricane as it approaches the Big Island.

HAZARDS AFFECTING LAND

----------------------

Key messages for Tropical Storm Lala can be found in the Tropical

Cyclone Discussion under AWIPS header HFOTCPCP2 and WMO header

WTPA42 PHFO.

WIND: Hurricane conditions are expected on the Big Island of Hawaii

by early Saturday, with tropical storm conditions possible in Maui

County by late Saturday. Wind speeds atop and on the windward

sides of slopes and mountains are often up to 30 percent stronger

than the near-surface winds indicated in this advisory, and in some

elevated locations could be even greater.

RAINFALL: Tropical Storm Lala is expected to produce rainfall totals

of 8 to 12 inches across Maui and the Big Island with maximum totals

of 25 inches possible across the Big Island. Rainfall totals of 4

to 6 inches with maximum amounts of 8 inches across the remainder of

the island chain. This rainfall may produce life-threatening

flooding and mudslides, especially in areas of steep terrain.

For a complete depiction of forecast rainfall associated with

Lala, please see the National Weather Service Storm Total Rainfall

Graphic available at hurricanes.gov/graphics_cp2.shtml?rainqpf

STORM SURGE: The combination of a dangerous storm surge and the

tide will cause normally dry areas near the coast to be flooded by

rising waters moving inland from the shoreline. The water could

reach the following heights above ground somewhere in the indicated

areas if the peak surge occurs at the time of high tide...

Hawaii...1 to 3 ft

The deepest water will occur along the immediate coast, where the

surge will be accompanied by large and dangerous waves.

Surge-related flooding depends on the relative timing of the surge

and the tidal cycle, and can vary greatly over short distances. For

information specific to your area, please see products issued by

your local National Weather Service forecast office.

For a complete depiction of areas at risk of storm surge

inundation, please see the National Weather Service Peak

Storm Surge Graphic, available at

hurricanes.gov/graphics_cp2.shtml?peakSurge.

SURF: Swells generated by Lala are expected to reach the east-facing

shores of the state on Friday, spreading westward and building

through the weekend. These swells are likely to cause

life-threatening surf and rip current conditions. Please consult

products from your local weather office.
