What are the effects of wind in public storm warning signal #1?

public storm warning signal #1 Hold on tight, folks! We’re about to delve into the fascinating world of wind and its impact on public storm warning signals. You may think that a simple gust of wind is nothing more than a nuisance, but every little detail counts when forecasting severe weather conditions.

In this blog post, we’ll explore the effects of wind in public storm warning signal #1 and discover how meteorologists use this critical information to keep us informed and safe during extreme weather events. So buckle up and prepare for some serious science – things are about to blow your mind!

What is wind?

The wind is one of the most important weather factors in determining the severity of a thunderstorm. It is the force that drives the movement of air masses and can influence thunderstorms’ formation, strength, and direction. The effects of wind on thunderstorms can be divided into two categories: surface wind and upper-level wind.

Surface wind is the wind at ground level. It is generally blowing from areas of high pressure to areas of low pressure and is a major factor in determining how severe a thunderstorm will be. If surface winds are strong, they can help to sustain and intensify thunderstorms. On the other hand, if surface winds are weak, Thunderstorms may not be able to develop or may quickly dissipate.

The upper-level wind is the wind above the surface of the earth. It plays a role in both the development and dissipation of thunderstorms. Upper-level winds can help lift air masses and create instability, leading to thunderstorm development. However, if upper-level winds are too strong, they can also disrupt thunderstorms and cause them to dissipate.

What is the public storm warning signal #1?

Winds of 30 kilometers per hour (kph) to 60 kph are expected within 12 hours. This is the public storm warning signal #1.

The effects of wind on public storm warning signal #1

As the wind increases, so does the possibility of damage. The National Weather Service issues a Wind Advisory when sustained winds of 30 to 39 mph, or gusts of 45 to 57 mph, are expected.

A High Wind Warning is issued when sustained winds of 40 mph or higher or gusts of 58 mph or higher are expected. A Wind Chill Warning is issued when the wind chill temperature is -35°F or colder. A Gale Warning is issued when sustained winds of 34 to 47 knots (39 to 54 mph), inclusive, are forecasted to occur for at least one hour or frequent gusts equal to or exceed 50 knots (58 mph). A Storm Warning is issued when sustained winds of 48 knots (55 mph) or greater are forecasted to occur for at least one hour and frequent gusts equal to or exceed 63 knots (73 mph). 

The effects of high wind can include:

  • Downed trees and power lines.
  • Blowing dust can reduce visibility.
  • Washing vehicles off the road.

High wind can also cause property damage, such as damaged roofs, siding, and windows. In extreme cases, high wind can result in structural damage to buildings.

How to stay safe during a public storm warning signal #1

When a public storm warning signal #1 is issued, a tropical cyclone approaches, and winds of 62 kilometers per hour (30 knots) or more are expected within 12 hours. Here are some tips on how to stay safe during this time: 

– Stay indoors and away from windows.

– If you are outdoors, seek shelter in a sturdy building.

– Avoid coastal areas and river mouths.

– Be aware of flying debris.

– Keep tuned to the radio or TV for updates on the situation.


Public storm warning signal #1 is an important tool to alert the public of potential danger from wind-caused storms. Understanding and recognizing the effects of wind on this signal helps people stay safe in potentially hazardous situations.

With these effects in mind, it’s important for anyone who lives or works near a coastline to pay attention to public storm warning signals and plan accordingly. You can keep yourself and your loved ones safe during high winds by staying informed and aware.
