Multiple Eastern Pacific records have fallen.

Firstly:

Number of category 5 days, Eastern Pacific. 2026 has broken the record for highest number of C5 days. A C5 day represents 4 separate tropical cyclone full advisory packages of at least 140 kt strength - because full advisories represent 6-hour intervals. In other words, if say advisories #11 through 14 of a tropical cyclone show a 140+ kt intensity - that would be one category 5 day.

Second:

30-day Accumulated Cyclone Energy generation, Eastern Pacific.

ACE is an metric in which tropical cyclone strength is integrated over time. It's the premier metric used by meteorologists to categorize hurricane seasons. Tropical storm, hurricane, and major hurricane quantity are not considered. When it comes to classifying a season as "below", "near", "above"-average, or hyperactive, ACE and ACE alone matters.

The Eastern Pacific has generated more ACE in the previous 30 days than during any other 30-day period in our records.

Finally:

For cumulative ACE, EPAC is currently in second place, behind only 1992, and just ahead of 2018 (the seasonal record holder). 2018 finished with 319 units - the highest amount on record. 2026 is maintaining a literal record-pace. But it still has a long way to go before threatening 2018s' seasonal record.

2026 Atlantic hurricane season at record-low activity

Today, September 10th, conventionally marks the peak day of hurricane season. About 50% of hurricane activity occurs before todays' date, and about 50% after.

And what a pitiful season it has been. Here are the top 10 least active seasons through September 10th, based on Accumulated Cyclone Energy (ACE):

  1. 1986: 12.3 units

  2. 2002: 12.1 units

  3. 2013: 12.0 units

  4. 1994: 11.0 units

  5. 1982 (tie): 10.7 units

  6. 1988 (tie): 10.7 units

  7. 1962: 10.3 units

  8. 1983: 9.5 units

  9. 1984: 7.8 units

  10. 2026: 4.4 units

Okay, so how did these seasons end?

Same seasons in order, but through the entire year:

  1. 1986: 35.8 units (below-average season)

  2. 2002: 68 units (below-average)

  3. 2013: 36 units (below-average)

  4. 1994: 32 units (below-average)

  5. 1982: 31.5 units (below-average)

  6. 1988: 103 units (near-average)

  7. 1962: 50.5 units (below-average)

  8. 1983: 17.4 units (below-average)

  9. 1984: 84.3 units (near-average)

  10. 2026: TBD

Not looking good for trackers. 1988 was a Strong La Nina year, functionally the diametric opposite of this season. No late-season recovery like 1988 should be expected, as the intensifying El Nino should keep things shut down. Similarly, 1984 began with La Nina. The La Nina decayed into cool-neutral during mid-year, but La Nina redeveloped in Autumn. So. Every season either had La Nina conditions involved (opposite of this year) or ended below-average. None ended above-average.

Vertical wind shear

Vertical wind shear describes the difference in magnitude and direction of wind flow between different altitude levels of the troposphere. You can think of wind flow in each altitude layer as its own individual vector, and the greater the difference when you subtract these vectors, the higher the wind shear.

Tropical cyclones require low vertical wind shear to strengthen. This is because the circulation/vortex of a tropical cyclone is vertically "deep", aka tall. It extends from the surface to near the tropopause in mature and powerful major hurricanes. The stronger the tropical cyclone, the taller its circulation is. Weaker tropical systems such as depressions or tropical waves exhibit shallower circulations.

A tropical cyclone requires its vortex to be vertically aligned and upright in order for the processes which fuel it to remain efficient and active. The release of latent heat, from thunderstorm activity (convection), is what fuels the warm-core of a tropical cyclone. This occurs due to the vertical transfer of heat, but when wind shear is present, the circulation of a tropical cyclone becomes tilted with height. This decreases the efficiency of this process, leading to a halting of intensification or weakening of the tropical cyclone.

When vertical wind shear becomes even stronger, this process is halted entirely. The circulation becomes so tilted that the low-level circulation and mid-to-upper-level circulation become increasingly displaced. If wind shear becomes strong enough, these two separate portions of the circulation can become totally separated. This is called "decoupling" and is the tropical cyclone equivalent of decapitation. Recovery would take many days and still would happen only IF conditions become favorable again, because the tropical cyclone would have to vertically rebuild its circulation almost from scratch.

Here is a gif which best shows this process unfolding. This is tropical storm Chris of 2006. 2006 was also an El Nino season, with correspondingly high vertical wind shear across the Tropics.

https://upload.wikimedia.org/wikipedia/commons/e/e4/Chrissplitloop.gif?utm_source=commons.wikimedia.org&utm_campaign=index&utm_content=original

In this gif, the surface circulation of the storm is tracking at about 300 degrees, or WNW. However, wind flow above the surface circulation is strongly out of the north. These northerlies push on the mid-level circulation and attendant vertically tall thunderstorm activity, displacing it towards the south. The shear is sufficiently strong to decouple the system, and you can see Chris continue WNW as all of its thunderstorm activity is violently stripped away.

From NHC advisory #11 on Chris:

>CHRIS IS BECOMING DISORGANIZED IN A HURRY. SATELLITE IMAGES INDICATE THAT THE LOW-LEVEL CENTER HAS BECOME DETACHED FROM THE THUNDERSTORM ACTIVITY DUE TO NORTHWESTERLY SHEAR...AND THIS WAS CONFIRMED BY FIXES FROM AN AIR FORCE RECONNAISSANCE PLANE. THE MINIMUM PRESSURE HAS RISEN TO 1010 MB AND THE MAXIMUM FLIGHT LEVEL WIND REPORTED SO FAR IS ONLY 38 KNOTS.

Advisory #12:

>THE COMBINATION OF DRY LOW- TO MID-LEVEL AIR AND SHEAR...ASSOCIATED WITH AN UPPER-LEVEL CYCLONE THAT DROPPED SOUTHWARD INTO CHRIS...HAS TAKEN ITS TOLL ON THE TROPICAL CYCLONE. CHRIS IS DEVOID OF DEEP CONVECTION WITHIN ABOUT 75 N MI RADIUS OF THE CENTER.

El Nino increases vertical wind shear over the Atlantic tropics. This is due to increased upper-level westerly flow across the Caribbean sea and western to central tropical Atlantic due to outflow from Eastern Pacific hurricanes as well as a shift in the Walker Circulation itself. Additionally, lower surface pressures in the Eastern Pacific sharpens a pressure gradient with higher pressures in the Atlantic, which strengthens the low-level easterly trade wind flow. Trade winds are naturally strong in the Caribbean Sea due to the geography of the Greater Antilles acting as a "funnel", which forces trade winds to "diverge", or accelerate. Additionally, the proximity of the Caribbean Sea means that the anomalously strong upper-level westerlies are particularly significant. Collectively, this results in the Caribbean experiencing the strongest anomalously hostile conditions yielded by the presence of El Nino, more so than anywhere else in the Atlantic basin. This is why the Caribbean Sea has been devoid of all activity this year.

In fact, vertical wind shear has been at all time highs in the Atlantic.

https://i.imgur.com/m2NH3VK.jpeg

Area-averaged vertical shear is far stronger than even the last super El Nino of 2015-16. 2026 is well ahead of second place (1979). This is the primary reason why this season is so dead, and it's not going to meaningfully change since El Nino is so strong and continues to only intensify further.

https://i.imgur.com/F2wbA6a.png

Current vertical wind shear values are comparable to values observed in June during above-average hurricane seasons. That's pretty remarkable considering we are right at the peak of the season, now.

Sorry for the yap, I just felt like writing something today.

From Tomer Burg: controllable balloon navigated above typhoon Dolphin, descended into the eye, and recorded multiple vertical profiles of the troposphere whilst circling the eye. This mission is the first of its kind.

Utility Runewords

What are some underrated runewords used for Utility or just in general? I have my list of examples:

Edge, a dirt cheap (Tir+Tal+Amn) in any 3os Bow runeword. Edge provides 15% Reduced Vendor Prices, making it an invaluable Switch for anyone Gambling or buying crafting materials like Amulets/Gloves/Rings.

Harmony, a relatively inexpensive (Tir+Ith+Sol+Ko in any 4os bow) runeword, this provides a couple useful-in-niche-situations benefits:

For starters, it gives 25 Charges of level 25 Revive.

Next, it rolls +2-6 to Valkyrie skill. Collectively, these summons could be very useful in certain situations.

But the main highlight to Harmony is the level 10 Vigor aura. If you're not already a Paladin with native access to Vigor, and before you've got your Enigma, Harmony is an incredible mobility runeword you can have on Switch for when you need to get around faster. Vigor is also very helpful for navigating in town, where teleport is disabled, regardless.

Insight well, it's the opposite of "underrated". I know it, you know it, my grandmother knows it; everyone knows it. With a level 12-17 Meditation aura, this dirt cheap (Ral Tir Tal Sol in any 4os polearm or bow) runeword gives ridiculous mana regeneration.

Rhyme, another cheap (Shael+Eth) runeword, in any 2os shield. A whole slew of useful mods: 20% increased chance of blocking, +25 allres, 25% magic find, and the coveted Cannot Be Frozen.

Smoke, not too expensive (Nef+Lum) in any 2os armor. With 18 charges of level 6 Weaken, 20% faster hit recovery, and the primary feature of an amazing +50 allres, this armor is amazing.

Lawbringer the most expensive runeword on this list (Amn+Lem+Ko), it should still be pretty affordable for almost all d2 players. Made in any 3os Sword, Hammer, or Scepter, this thing is goddamn amazing. For starters, it gives +10 dexterity and 7% life leech. It adds 150-210 Fire and 130-180 Cold damage. It boasts +75% gold from monsters and -50% target defense. But now for the amazing mods:

It provides a level 16-18 Sanctuary aura, fantastic against Undead monsters specifically. Next, it provides the wonderful Slain Monsters Rest In Peace, a must have for Nihlathak runs (for example). Finally, Lawbringer provides a 20% chance to cast level 15 Decrepify on striking. Lawbringer is therefore an excellent switch for the SMRIP and Decrepify, when the situation demands them.

Wealth another fairly inexpensive runeword (Lem+Ko+Tir), this 3os armor runeword gives 300% gold find and 100% magic find. it doesn't do much else, literally only +10 dexterity and +2 mana after each kill (from the Tir rune), but can be very helpful.

Black Inexpensive budget Ubers weapon. For Thul+Io+Nef in any 3os Clubs/Hammers/Maces (you can shop 3os Flails from fara in nightmare difficulty btw, it only takes a few minutes), you get an amazing 40% crushing blow and 15% increased attack speed. It also provides a decent +10 vitality and 200 attack rating. It does have some goofy mods like 12 charges of level 4 Corpse Explosion, and the not-fondly-looked-upon Knockback. Against bosses though, the Knockback shouldn't be a problem.

Cure Whilst this is also not too expensive (*Shael+Io+Thul), this 3os helmet runeword is ladder-only if you play online. However, it provides a level 1 Cleansing aura. This runeword is commonly utilized on an act 2 Prayer mercenary with Insight, because the Meditation aura from Insight and the Cleansing aura from Cure synergize with Prayer, effectively tripling the health regeneration.

What are some other underrated runewords? I'm sure I'm missing some!

First time ever doing Ubers.

https://i.imgur.com/1sUeWFD.png

I've played off and on since the mid 2010s. I did my first ever Ubers today.

Beat it first attempt. To be honest... it was shockingly easy. I think I over prepared, haha.

Gear:

Weapon: Grief

Shield: Exile in eth sacred targe

Ammy: Maras +30 allres

Helm: GFace

Armor: Treachery swap for Fade proc, Duress otherwise

Gloves: Dracul's Grasp

Belt: TGods vigor

Boots: Gore Rider (awesome boots!)

Rings: Raven Frost, Wisp Projector

Swap: Call to Arms + Spirit

and a couple of pcomb GCs, a +45 life +30 lightning res GC i found today, a bunch of small charm +18-20 to life

Skills:

I'm a hammerdin, so.

1 pt Smite

1 pt Fanaticism

1 pt Salvation

So, using Smite + Fanaticism. Duriel was a pushover. Izual seemed scary until I realized my Battle Orders had dropped. Lilith wasn't as bad as I expected, but I prepotted 4 Antidote potions when I found her room. I used the fire pentagram on the tower to reproc Fade from treachery (had it and extra pots in my cube with me)

Then for Tristram. I walked up and left and was able to pull Mephisto. Immediately switched to Salvation and smited him down. I was so nervous for this moment, and yet he couldn't do shit to me. After he dies, I smite the minions down, I go back to Fanaticism, go south and east, and pull Baal. I smited him down, and then charged in the center right at Diablo. He was also easy to smite down, but I had a few physical immune mobs near me which made a sketchy situation. I couldn't damage them and I didn't have Enigma with me, so I was trapped. I was able to use blessed hammer to escape.

And cause I live life dangerously, I decided fuck it and let me merc tag along. Well, he survived literally the entire thing, lol. Shout out to Emilio!

Nothing that hasn't been said a million times already, I know. But it's my first time and I'm super hyped. Now, do I gamble by rolling the torch, or do I just sell it unid?
