Kryptonite Weather with some awesome info about flood forecasting!

Let's dive into something that's making flood forecasting even more powerful than ever before. You've heard us talk about flood warnings and the big picture, but now let's get into the nitty-gritty of why a new technology called event-driven flood inundation mapping (FIM) is a game-changer on a scale most people don't even realize.

It's one thing to hear, "The river will crest at 25 feet." It's another thing entirely to see a map that shows exactly which streets, houses, and critical infrastructure will be underwater at that level.

For years, we've had "static" flood maps—maps that show where a 100-year or 500-year flood could reach. They're useful for planning, but they don't help much in a real-time, unfolding crisis. 100/500 year flood event terminology doesn't really provide much, if any, context to the average citizen.

This new technology, developed by the National Weather Service's National Water Center and its partners, is different. It's event-driven, which means it's not a static picture from the past. It's a living, breathing map that shows you the future.

(The following text is from a NOAA article you can find here:https://www.weather.gov/media/owp/operations/2025_NWS_OWP_FIM_Rollout_Flyer.pdf )

The longstanding demand for event-driven flood inundation mapping (FIM) has increased dramatically in recent years as a high value source of actionable information for emergency and water resource managers to prepare, mitigate, and respond to
flood impacts.

In response, the National Water Center (NWC) of the National Weather Service (NWS), in coordination with NWS
River Forecast Centers (RFC) and Weather Forecast Offices (WFO) along with Federal and other partners, has developed and
demonstrated high-resolution inundation modeling capabilities which complement and expand upon existing static FIM libraries
providing geo-referenced visualizations of forecast flooding extent at the continental scale.

New inundation mapping capabilities translate analysis and
forecasts of streamflow into operational maps that communicate
impact by showing where flooding may occur.

Flood inundation mapping will be provided based on the RFC
streamflow forecasts as well as from the National Water Model
(NWM) streamflow analysis and forecasts. RFC-based inundation
mapping will be provided at and downstream of official RFC
forecast locations and will provide a forecast of maximum inundation extent over the next 5 days.

"Had I had this tool in 2011, we would have had a larger evacuation area established earlier, would have moved emergency assets out of the flood zone, pre-positioned support resources
and been able to provide better information to
the residents of the affected area."

- New York state emergency manager from 2021 tabletop exercise

(End of excerpt)

So, the next time you see a flood inundation map, remember it's not just a picture. It's a powerful tool that translates complex scientific data into actionable, life-saving information. It's the difference between saying "be careful" and "here is exactly what you need to do to stay safe." It's a leap forward in how we prepare for and respond to the most common natural disaster on the planet.

⚡ Severe Weather Outlook – Saturday, September 6, 2025

UPGRADE!

The Storm Prediction Center has issued a Slight Risk (Level 2/5) for severe thunderstorms from eastern Pennsylvania and New Jersey into New England this afternoon.

📍 Northeast (Main Focus)

Threats: Damaging winds & a tornado or two

A strong disturbance and cold front will trigger scattered to numerous storms by mid-to-late afternoon.

Supercells are possible in southern New England into southern Maine, where tornado probabilities have been highlighted.

📍 Mid-Atlantic → Carolinas/Georgia

Threats: Strong to locally severe wind gusts

Scattered storms will develop into a few bands during the afternoon, but overall severe potential is lower.

Severe risk diminishes after sunset as storms weaken.

⚠️ Stay alert if you are in the risk zones, and always have multiple ways to receive warnings.

🚨 Tropical Weather Outlook – 8 AM EDT (Tue Sep 2, 2025) 🚨

A tropical wave located south of the Cabo Verde Islands in the far eastern Atlantic is producing disorganized showers and thunderstorms.

🌊 Development chances:
Next 48 hours: 30% (Low)
Next 7 days: 70% (High)

This system is expected to move west to west-northwest at around 15 mph across the Atlantic. A tropical depression is likely to form later this week or into the weekend.

While no immediate land impacts are expected, this is a system to watch closely as it tracks across the Atlantic.

⚠️ Stay tuned for updates as conditions evolve!

🍂 Today marks the first day of meteorological fall—the season of crisp mornings, golden leaves, and cozy transitions. Unlike astronomical fall (which starts later this month), meteorological seasons follow the calendar more closely, making September 1 the official kickoff to autumn in the weather world.

Whether you’re lighting that first pumpkin-scented candle, swapping iced coffee for hot, or just watching the trees begin to blush—fall is here in spirit and science.

Let the layering begin. 🍁🧣

🌌✨ Heads-up, sky gawkers!

A spectacular solar storm is barreling toward Earth just in time for Labor Day, and if the forecasts hold, a dazzling aurora display may dance across much of the northern U.S. and Canada. Get ready to keep your eyes peeled, blankets packed, and cameras charged! 📸🌠

☀️ What’s Going On?
A powerful “cannibal CME” (coronal mass ejection)—two solar eruptions merging into one supercharged storm—is expected to arrive late Sept 1–2, 2025. It could spark Strong (G3) to Severe (G4) geomagnetic storming! 🌍⚡

Where Can You See It?
Canada & Alaska = PRIME viewing 🎉

Northern U.S. states like Michigan, Wisconsin, Minnesota, the Dakotas, Montana & Washington. Possible visibility as far south as New England, Iowa, Oregon & Connecticut.

👉 Look northward under dark, clear skies between 9 PM – 3 AM, with the best time around midnight.

👀 Best Viewing Tips
Escape city lights
Watch the weather for clear skies
Bring warm clothes, a chair, and patience

📸 How to Photograph Them
Phone: Use Night Mode, tripod, ISO 800–1600
DSLR/Mirrorless: Wide-angle lens, f/2.8–f/4, shutter 5–20s, ISO 800–3200
Shoot in RAW for best editing

💫 Why This Storm Is Special
This is a rare cannibal CME—meaning auroras could be extra bright, extra widespread, and unforgettable

👉 Don’t miss one of the best aurora shows in years!
Keep checking NOAA & aurora dashboards for real-time updates.

🍂🍁 Happy Meteorological Fall! 🍁🍂

It may only be September 1st, but that means we’ve officially flipped the calendar into Meteorological Fall! That’s the signal to start breaking out the blankets, cozy flannels, fall decorations, and of course—s’mores by the fire. 🔥🍫🌙

We’ve been treated to a little “false fall” here in Pennsylvania and Ohio with some lower temps, but don’t pack away the summer gear just yet—the warmth is making a comeback this week. ☀️

Still, the good news is… REAL fall is just around the corner! Cool, crisp mornings, colorful leaves, and pumpkin spice everything will be here before we know it. 🎃🍎🌾

Who else is ready for sweater weather? 🙋‍♀️🍂

🌪️✈️ Did you know?

Back in the 1940s, when the very first Air Force Hurricane Hunters started flying into storms, they had a unique tradition…

Instead of numbers or codes, pilots and crews would sometimes nickname hurricanes after their wives, girlfriends, or significant others. This practice was informal, but it made the storms easier to talk about than just saying “the big storm south of Cuba.”

👉 That little habit actually helped spark today’s official hurricane naming system! In 1953, the U.S. Weather Bureau began formally naming Atlantic storms with women’s names, and by 1979 men’s names were added too.

What started as a personal touch in the cockpit has now become a worldwide standard for keeping track of tropical storms and hurricanes. 🌍

⚡️ Next time you hear a hurricane name, remember, it all began with a few Air Force crews showing a little love while chasing some of the most dangerous storms on Earth.
