Reported hail and wind

Where hail was actually reported.

The National Weather Service already publishes every hail, wind and tornado report a spotter files. FL Permit Pay puts the ones near your addresses on a map you can read in a driveway.

Get started See how it works

These are observations of the weather at a point and a time. FL Permit Pay never states that a roof is damaged, that a claim exists, or what hail of any size does to a roof.

One report, four facts

Step 1What was reportedHail, damaging wind, or a tornado. Three feeds, one map.
Step 2WhenThe time the report was filed, shown in Florida local time.
Step 3WhereA latitude and longitude, and how far your address is from it.
Step 4How bigHail carries its size in inches. Wind carries no number, because the feed does not state its unit.

How the work moves

A hail map is only useful if you can defend every number on it.

The value is not the colour. It is that you can knock on a door and say exactly what a federal agency recorded, and be right.

Step 1
Coloured by reported hail size
Each square is ten miles across and takes the colour of the largest hail size reported inside it, in inches. The legend prints the inches.
Step 2
Every square traces to its reports
Tap a square and read the reports underneath it, each with its time and county. Nothing is summarised past the point where you can check it.
Step 3
Which of your addresses were near
Reports of the same kind that happened close together in time and place are grouped, and your geocoded jobs are matched against the group with the distance to the nearest actual report.
Step 4
The line between reports is labelled as ours
Joining scattered reports into a track invents coverage between them. An address that only qualifies because of that drawn line is marked as sitting between reports, not under one.

What this does not do

It does not say a roof is damaged, that damage is likely, that a homeowner has a claim, or what hail of a given size does to a shingle. There is no verified rule connecting hail size to roof damage, so FL Permit Pay does not encode one. It reports what NOAA recorded and stops there.

It shows no wind speed. The public feed does not state whether its wind numbers are miles per hour or knots, and the difference is real, so FL Permit Pay prints no number it cannot defend. Wind reports still appear on the map with their time and county.

It is not radar. These are reports filed by trained spotters, emergency managers and the public, so coverage follows where people were, not where the storm was. Many wind reports carry no measurement at all because somebody saw damage and had no instrument; those are shown as reported without a size, never as zero.

It searches one fifty-mile circle around the middle of your located addresses, over a window you choose, and it tells you how many of your addresses fell outside that circle. A job with no map location cannot be placed and is counted separately.
