Our Process

1. Winter Storm

A winter storm occurs. Snow removal contractors clear and treat their sites.

2. Measurements

Several snowfall measurements are taken and reported to public and private authorities.

3. Research

A WeatherWorks meteorologist begins in-depth research of the snowstorm, noting the timing, intensity, temperatures, and winds.

4. Data Gathering

Snowfall observations are collected by our meteorologists from public and private sources including official storm spotters, highway departments, schools & colleges, social media, and web cam videos.

5. Analysis & QA

We then analyze the snow totals, looking to make sure the observations were taken properly and at the right time for each site.

6. Snowfall Totals

Snowfall totals are generated for each city and ZIP code. A final quality control and review of each snow total is performed to ensure accuracy.

7. Email in 48 hrs

Certified Snowfall Totals are published to our database within 48 hours of the conclusion of the storm. Clients are notified via email so they can login and retrieve their specific snow totals.

8. Quick Invoices

Create or validate invoices fast with our detailed snowstorm reports. Our Certified Snowfall Totals API allows for automatic integration of our snow totals into billing software.

9. Professionalism

Satisfaction guaranteed! Eliminate disputes and maintain / strengthen professionalism between all parties involved.
