It's that time again ... enter your forecast for seasonal totals of storms, hurricanes, and major hurricanes (in the North Atlantic basin) ... using NOAA official counts as our contest guide. Include any named storms already in the books by 06z June 7th in your total (as of now, count is 0/0/0). 1991-2020 average values 14/7/3 ... 2025 seasonal forecasts from various experts average 17/9/4 (so far). I will include a few of these as of June 7 as non-entries for ranking against our forecasts (without changing our contest ranks). I extended the entry deadline based on the situation as of 06z June 8. You can edit or revise any entries up to final deadline (11th 06z), no need to bring attention to edits as I won't be trying to create a table of entries until deadline is passed. Boards.ie weather forum and Net-weather (UK) will be invited to participate. Ranks will be provided (a) over all entries and (b) within forums, or fora if anyone here is a Latin purist. 2024 winner was Kirkcaldy Weather of Net-weather. Good luck !

I think with that reservoir capacity question, 100% is an optimal design level, 110% is probably a few feet above 100% and barely noticeable to a casual observer, but an overflow situation is likely to be 135% or even 150% of capacity, there's a margin for surplus capacity and managers will tolerate it especially if they foresee lower levels in the near future. Depends on local terrain and size of dam holding the reservoir in place.

My usual end of month appearance to remind contest entrants (main forum) of approaching deadline for MAY forecasts. On subject of those power outages, I noted that strong winds were blowing in one region of southern Spain and light winds prevailed elsewhere, at time of problems, and during very warm and sunny conditions generally -- could be an imbalance in wind energy contributions to grid causing oscillations.

Eastern states long overdue for a very hot summer and nobody would be surprised if it came in 2025.

The maps alone would be sketchy at best, but we also have some other clues from obs elsewhere, I would imagine the cold NW flow was good for a few snow showers and then the organized event by Apr 17-18 was likely a cold rain in present NYC metro and wet snow in n NJ and lower elevations se NY.

NOAA now has maps going back to 1836. They are available on the weather forum wetterzentrale.de and here's a link to Apr 16, 1849 at 12z. (click on archives at wetterzentrale's home page). Toronto wx data (starts 1840) indicates very cold air mass, 29/16 and 1.5" snow on Apr 15, 30/20 dry on Apr 16. Caswell in Providence RI recorded 24F as low for Apr 16 and near 37F for a max, no precip noted and says "clothes on line froze in a strong NW wind." Low DonS references gave 1.05" rain there Apr 17-18, 40s F. http://wetterzentrale.de/reanalysis.php?map=2&model=noaa&var=1&jaar=1849&maand=04&dag=16&uur=1200&h=0&tr=360&nmaps=24#mapref

I found a wx map for Apr 16 1849, looks like NYC may have seen some snow or sleet showers in a very cool NW flow, but the s.e. coastal snow was associated with a low off the coast that did not move n.e., it weakened and the cold n.w. flow continued over NYC region for two days. Probably 4/16/1849 was close to 39/29 .05" prec 0.1" snow. NW 20-35.
