StormCrownHD is named for a truth older than any radar: the storm is powerful, but it is not sovereign. Jehovah commands wind and sea, and the clouds are the dust of His feet.
We read the storm with the best science available: official forecasts, radar, satellites and warnings from the National Weather Service and NOAA. Then we explain it plainly, so you can stand watch over the people and places you love.
Read the storm. Stand watch. Stay ready.
“Jehovah sat as King at the Flood; Yea, Jehovah sitteth as King for ever.”
The lore
Our theme line, “Jehovah, Lord over the storm,” is drawn from Psalm 29 and Nahum 1; it is a summary, not a quotation. We quote the American Standard Version of 1901, which renders the divine name as Jehovah. The storm is powerful, but it is not sovereign, and that is why we can face it with calm eyes.
“…Jehovah hath his way in the whirlwind and in the storm, and the clouds are the dust of his feet.”
“…Who then is this, that even the wind and the sea obey him?”
The Eye brings radar, satellite, outlooks and alerts onto one live map, and The Briefing explains them plainly. Thunder and lightning have always been read as a voice; we read them with instruments.
“The voice of Jehovah is upon the waters: The God of glory thundereth, Even Jehovah upon many waters.”
The Watch keeps the official alerts in view, and Places watches the people and places you love so you can rest.
“I will stand upon my watch, and set me upon the tower, and will look forth to see what he will speak with me…”
The Ready hub turns official guidance into checklists for before, during and after the storm.
“A prudent man seeth the evil, and hideth himself; But the simple pass on, and suffer for it.”
When no alerts are active, we say so plainly. Calm after the storm is worth noticing.
“He maketh the storm a calm, So that the waves thereof are still.”
Faith and forecast
Our faith shapes our posture: calm, watchful, unafraid. It does not shape the forecast. Every forecast, watch and warning here comes from official scientific sources, cited and timestamped, and nothing on StormCrownHD claims to predict weather by divine authority.
The science
StormCrownHD does not make its own forecasts. It gathers official products from NOAA and the National Weather Service, keeps their timestamps, and shows every layer with its source and freshness. When a feed is late or down, we say so on the page rather than hiding it.

Our approach to AI
Weather data is precise but rarely plain. AI helps translate it, with firm limits so the official word always stays official.
Every AI explanation carries this label
The Briefing and The Guide are written by Claude, an AI model from Anthropic, from the official data StormCrownHD has already gathered: NWS forecasts, alerts and forecaster discussions, plus SPC, NHC and WPC products. It explains that data in plain language. It never makes its own forecast.
Explanations link to the official products they draw on, with issuance times, so you can always read the original for yourself.
AI-written text carries a visible label saying it is an AI explanation, when it was written and how fresh its data is. When the AI is unavailable, The Briefing says so and shows an automated summary of the official data instead.
When a watch or warning is in effect, the official NWS text and instructions lead. The AI never issues, upgrades or cancels an alert, and it points you to local officials for decisions about safety.
StormCrownHD is not an official warning service. Alerts shown here come from the National Weather Service, but delivery can be delayed. Follow instructions from the NWS and local emergency officials, keep Wireless Emergency Alerts or a NOAA Weather Radio on, and call 911 in an emergency.
Alerts can reach you on StormCrownHD minutes after they are issued, and notifications depend on your device, browser and connection. Wireless Emergency Alerts and NOAA Weather Radio do not.
