The @nws.noaa.gov offices are starting to notice an uptick in #tropical #weather hype. Please ensure you get your forecast information from reliable sources, and not those attempting to just gain views or clicks. #PSA #HurricaneSeason2025

We desperately need headline caveats these days that fit in a single post.

Example: Good news about satellite data availability*

*they are "fixing" a problem of their own making AND it would have been better to do absolutely nothing in the first place rather than undermine confidence and stability

No, Hurricane Activity Is Not Behind Schedule Right Now Is the Atlantic hurricane season off to a slow start? By some metrics perhaps but not really. A meteorology expert explains.

I keep seeing questions and narratives that the 2025 Hurricane Season is off to a slow start. My explanation in Forbes dot com on why I say "Not Really." Cites my colleague @michaelrlowry.bsky.social

Thanks for confirmation. I had a feeling but that podcast has done some wild episodes in the past which are fascinating.

Disturbance Moves Inland Over Louisiana while Tropics Stay Quiet Invest 93L slides into South Louisiana today, bringing periods of heavy rainfall and flash flooding through tomorrow

Despite all the flooding from abundant tropical moisture to start the hurricane season, tropical systems have so far struggled to organize or hold together. The overall season-to-date ACE is the lowest we've seen since the early season shutout of 2009. ⬇️

Love the floor to ceiling windows for those big ass sunsets. Also, the thing that struck me the most walking around was how beautiful that area around the botanical gardens is so to have that flow directly into the arena is going to be something else.

πŸ‡­πŸ‡· This might be my proudest achievement.
After playing at TuΕ‘kanac in Zagreb, Croatia and highlighting how this historically important court had fallen into disrepair, my video prompted the local government to renovate it and bring it back to life, returning it to its former glory.

Baltimore is seeing the city’s fewest homicides in 50 years. Here’s why. Multiple people have taken credit for the historic drop that mirrors a national decrease in violent crimes. Baltimore Mayor Brandon Scott says it’s due to a community-based approach to gun violence.

#Baltimore Mayor #BrandonScott invested in 42 summer youth camps, 29 literacy programs, extended the rec center hours to 11 p.m, planned block parties, opened the pools for safe fun, & opened several schools up for summer classes. Crime is down 62%. πŸ”₯πŸ”₯ www.washingtonpost.com/dc-md-va/202...

They are simply not up to the task of defending the constitution and the people of this country. I haven’t gone this far yet on this, but I’m done. They have taken an oath and a responsibility and they’re willfully, even joyfully abdicating it.

This is useful to read if you want a more nuanced understanding of the relationship between funding cuts and the flooding in Texas.

Forecasting issues:
- Flash flood forecasting and warning is difficult for a number of reasons
- Numerical models are generally poor at predicting warm-season convective precipitation (e.g., Novak et al. 2014)
- Small time and length scales add to the problem
- Very small differences between β€œevent” and β€œnon-event” days
- Must not only predict rainfall, but hydrology as well (NWS uses hydrologic models for this purpose) 
- Since most flash floods occur at night, warnings are not as effective (people are sleeping)
- Difficult to β€œrouse public concern” about rain, which is normally a benign weather event, as opposed to tornadoes and other severe hazards (Doswell et al. 1996)

Exactly. This is a slide from my mesoscale class on flash flooding (mainly just taken from Doswell et al. 1996)...this event hit every one of these bullets...

Based on some of the reactions and comments I am absorbing by average people and elected officials, I think there needs to be a serious explanation and lesson on what the limits of predictability are for floods like the one in Texas.

There have been claims that NOAA/NWS did not foresee catastrophic TX floods--but that's simply not true. This was undoubtedly an extreme event, but messaging rapidly escalated beginning ~12 hrs prior. Flood Watch mid PM, "heads up" outlook late PM, flash flood warnings ~1am.

Calvin and Hobbes is still one of the best parts of my childhood, and those comic strips hold up today.
