According to Con Edison, a whopping 1389 people without power: https://outagemap.coned.com/external/default.html And on Long Island, my Godmother said "lots of rain and a little wind."

The Central Pacific Hurricane Center decided this storm (Linda) got too weak yesterday, declared it post-tropical, and stopped issuing advisories. Let's check in today and...oh.  Let's see what the CPHC has to say and...oh.

It's a sign of things to come. As the earth continues to warm we will get stronger and stronger storms going further and further north. Hopefully individual areas can prep better than the states have been. :/

Platystemon posted:https://i.imgur.com/LKTvvcW.mp4 I seriously can't wait to wake up tomorrow morning. If there's still no tropical storm warning issued I'll laugh my rear end off. Edit: This is the same CPHC that got severely hosed up forecasting Iniki. Even more funny now since they have tools they couldn't have dreamed of then. I'll eat my hat if this landfalls as anything more than a weak tropical storm, but the CPHC has a documented history of getting poo poo wrong.

NWS Honolulu posted:Based on the latest track guidance, we believe the center of the low will be on Maui's doorstep some time after midnight HST. It will continue to bring its heavy rain and gusty winds across the rest of Maui County through early Monday morning. Unfortunately for Oahu, this means that by daybreak Monday, the weather will likely take a serious turn for the worst. Since the track of the low center could be just south of the island, flooding rains with heavy thunderstorms and gusty winds could make the morning commute very challenging. These conditions could persist for several hours, so there could be some issues with tree branches falling, clogged drains, and spotty power outages into Monday afternoon. These adverse weather conditions will also likely spread to Kauai during the daytime hours Monday, where thunderstorms could also produce flash flooding and strong gusty winds. Tomorrow is the first day of class at UH Manoa. Traffic is gonna be an absolute shitshow with this and nobody is prepared for it beyond the generic flash flood watches and wind advisories that often get ignored. CPHC really screwing the pooch with this by not issuing any sort of tropical storm warning.

Looks like wind shear is still beating the poo poo out of it but it also really, really wants to strengthen in spite of it.

I thought that was really interesting. I've only ever heard about or read about wind shear taking apart a storm. It's neat to see it in action. I still don't fully grasp what wind shear is though. That's caused by like wind shifting from higher elevation to lower and creating like a wind wall that the storm isn't strong enough to push though?

PostNouveau posted:I thought that was really interesting. I've only ever heard about or read about wind shear taking apart a storm. It's neat to see it in action. this an explanation of wind shear as it relates to a tropical storm: https://www.wunderground.com/hurricane/articles/wind-shear-explainer notably quote:The troposphere is the region of the atmosphere that our active weather is confined to, and extends up to about 40,000 feet altitude (a pressure of about 200 mb) in the tropics in summer. Hurricanes fill the entire vertical extent of the troposphere, and are steered by the average wind through this layer. When one hears the phrase, "wind shear is 20 knots over the hurricane", this typically refers to the difference in wind speed between 200 mb (the top of the troposphere, 40,000 feet altitude) and a layer where a pressure of 850 mb is found--about 5,000 feet above the surface. this won't help anyone that looks in the future but take a look at the nifty earth wind map: https://earth.nullschool.net/#current/wind/isobaric/850hPa/orthographic=-158.33,20.89,1748 I just grabbed a random point to the north of the low that has wind at the 850hPa level as 32knots with a direction of 110 degrees. its moving west at like 20 knots. Wind at 250hPa is 37 knots at 245 degrees. In other words the storm has a giant head wind so instead of the entire air mass "moving together" to the west the top part of the troposphere is blowing any water (energy) that makes it to that altitude away. this means the storm can't develop because all that energy isn't in one spot. in comparison if the high level wind was going with the storm at about the same rate then all that energy would stay in the same spot relative to the storm's movement and the storm could intensify. this is a more official wind shear map, the red 40/50 says theres a 40 to 50 knot difference between surface winds and upper level winds consistent with what I said above http://tropic.ssec.wisc.edu/real-time/storm.php?&basin=eastpac&sname=12E&invest=YES&zoom=4&img=1&vars=11111000000000000000000&loop=0 hobbesmaster has issued a correction as of 18:00 on Aug 23, 2021 |

I'm really confused about the no rotation part because it's not very hard to see the LLC rotating in those IR loops posted above lol

all lows rotate, thats what makes them a low well, sort of, its more that low pressure means theres a cyclonic rotation of the air (counterclockwise in the northern hemisphere), high pressure means anticyclonic (clockwise in the northern hemisphere)
