Last updated: 2023-09-06

When winter storms approach, knowing how to interpret precipitation forecasts step by step is crucial for safety and planning. Clime provides robust tools for following these forecasts, ensuring that users receive timely updates and actionable insights during winter weather events.

Summary

• Understand key terminology related to winter weather forecasts.
• Learn how to interpret different types of forecasts from watches to warnings.
• Use Clime’s features for accurate, real-time precipitation predictions.

What Is a Winter Weather Watch?

A Winter Weather Watch is typically issued within 24 to 72 hours before a hazardous winter weather event is expected. This alert indicates that conditions favor a significant winter weather event, such as snow, sleet, or freezing rain. Knowing this timeframe helps individuals prepare ahead of a storm, ensuring they have the necessary supplies and plans in place.

Types of Precipitation Forecasts

Forecasts can include various forms of precipitation, such as snow, sleet, or rain. Each type can dramatically affect how we prepare for winter storms:

• Snowfall Forecasts: Represented visually on a Point map, which illustrates projected snowfall amounts at specific locations.
• Mixed Precipitation Alerts: Indicate when different forms of precipitation may occur at different times, revealing potential issues like ice formation that can affect travel and infrastructure.

Understanding Watches, Warnings, and Advisories

• Winter Weather Watch: Signals the likelihood of hazardous conditions without specifics on severity or timing.
• Winter Storm Warning: Confirms that significant snow, sleet, or freezing rain will occur, helping you understand the urgency in preparing.
• Winter Weather Advisory: Used when winter weather could cause widespread travel difficulties but is less likely to be severe than conditions requiring a warning.

Utilizing Clime During Winter Storms

Clime enhances your ability to understand and act on winter weather forecasts:

How to Read Precipitation Amounts

The Point map from the National Weather Service (NWS) provides a visual reference for expected snowfall amounts, measured in inches. This graphic is updated frequently so you can track impending snowfall and prepare accordingly. It’s essential to monitor these maps as storms develop since they can change rapidly.
