← All conditions

Severe weather

planned

Tornado, hail, lightning and hurricane records — largely event reports rather than instrument readings.

Authoritative sources exist and publish continuously. Adapter not built.

What this lane covers

Tornado reports and paths

That a tornado was reported, where, and along what track.

event areal analysis

Hail size

Reported maximum stone size at a location.

event station analysis

Lightning strike location and time

Detected strike position and timestamp from a detection network.

measurement areal instrument

Hurricane track and intensity

Position, pressure and wind at each advisory.

model areal analysis

Warnings issued and when

That a warning was in force for a polygon at a time.

event areal analysis

How to read this page

event

Someone recorded that a thing happened. An observation, not a reading.

measurement

An instrument read a value at a place and a time.

model

An analyst or a model produced this from other data. It is a product, not a sensor.

areal

Covers an area, not a point. There is no nearest station, and we will not invent one.

station

Measured at a fixed station. The record discloses which one and how far it is from you.

analysis

An authoritative body's analytical product. Its uncertainty is the source's own.

instrument

Published by an authoritative operator of the instrument.

What we cannot compare

Most of this lane is event records, not measurements. A tornado report is an observation someone made, with a different provenance shape and different failure modes — absence of a report is not absence of a tornado, and the record must never be read that way.

Sources

Not named here yet. Candidate sources for this lane exist and are identified internally, but they have not been verified against the primary documentation — and an unverified source attribution on a public page is the exact mistake this company exists to avoid. They appear here when they have been checked, not before.

Worth knowing

Deciding whether event records belong in the same record model as measurements is open work. Until it is settled, nothing here is sold.

Where the answer is worth money

Hail damage claimed for a storm that missed. A lightning claim where the nearest recorded strike was miles away. A warning-time dispute over whether an evacuation was reasonable.

That framing is our analysis of where disputes arise, not a claim of fact about any matter.

Not captured yet

What would you need from severe weather?

We are not capturing this lane today, so there is nothing here to sell you and we are not going to pretend otherwise. What we do want is to know what you would actually ask it. Requests decide what gets built next — that is not a courtesy, it is how the order is set.
