What is a public storm warning signal #1 affected areas?


Are you curious about the public storm warning signal #1 and its affected areas? With typhoons and other natural calamities becoming more frequent, it’s essential to understand what this warning signal means. In this blog post, we’ll take a closer look at the definition of public storm warning signal #1 and where it can have an impact. So, let’s dive in!

What is Signal #1?

As we all know, tropical cyclones bring heavy rains and strong winds. These can uproot trees, damage houses, and cause severe flooding. To minimize the damage caused by these storms, the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) uses a public storm warning signal system. This system consists of 4 signals, with Signal #1 being the least serious. 

Signal #1 is raised when 30-60 kph winds are expected within 36 hours. This is enough to sway coconut trees slightly, and branches may fall. Light materials such as garbage cans may be blown away. The seas will be slight to moderate with 1.25-3 meters wave heights. 

Residents in areas under Signal #1 should monitor updates from PAGASA and be prepared for possible evacuation

The Different Types of Storms

There are four primary types of storms: thunderstorms, ice storms, blizzards, and hurricanes. Different weather conditions characterize each type of storm.

Thunderstorms are storms that are accompanied by thunder and lightning. They typically occur in summer and can bring heavy rains, strong winds, and hail.

Ice storms occur when precipitation falls as freezing rain or sleet, resulting in a coating of ice on trees, power lines, and roads. Ice storms can be hazardous, as they can cause power outages and make travel very difficult.

Blizzards are severe winter storms characterized by high winds and heavy snowfall. Blizzards can create whiteout conditions, making it difficult to see while driving.

Hurricanes are tropical cyclones that form over warm ocean waters. They typically occur in late summer or early fall, bringing high winds, storm surge flooding, and heavy rains.

What to do During Signal #1

If you are in an affected area, the first thing you should do is to shelter in a sturdy building and stay indoors. If you are outdoors, try to find a safe place to shelter. Once you are safe, stay there and only try to go outside once the all-clear signal has been given.

What is a public storm warning signal #1?

When public storm warning signal #1 is in effect, affected areas should expect winds of 30 to 60 kilometers per hour (kph) within the next 36 hours. This signal is usually issued when a tropical cyclone is 1,000 kilometers away from any part of the country.

What areas are affected by the public storm warning signal #1?

When a public storm warning signal is issued for an area, it means it is at risk of being affected by a tropical cyclone. The area most like to be affected by a tropical cyclone are coastal areas and areas further inland that are close to rivers or lakes.

Areas at risk of being affected by a public storm warning signal should take precautions to protect themselves and their property. This includes preparing for high winds and heavy rains and evacuating if necessary.

Residents in affected areas should pay close attention to the latest weather forecasts and warnings and follow the advice of local authorities.

How to prepare for public storm warning signal #1

When public storm warning signal #1 is issued, a tropical cyclone will likely bring destructive winds of at least 60 kilometers per hour (kph) within 18 hours. Affected areas should take necessary precautions and be prepared for the arrival of the tropical cyclone.

Necessary precautions include:

– Secure loose outdoor items and bring them indoors.

– Close windows, doors, and shutters.

– Turn off air conditioners.

– Fill up your vehicle’s gas tank.

– Stock up on food and water supplies.

– Charge all your electronic devices.

– Keep a battery-powered radio on hand to stay updated on the latest weather reports.


Public storm warning signal #1 means that the public in affected areas should be alerted and take necessary precautions due to imminent danger. Residents of affected areas need to know what this warning signal stands for to stay safe during extreme weather conditions. By understanding what Public Storm Warning Signal #1 entails, individuals can make informed decisions about their safety and well-being when storms hit their area.

The public storm warning signal number reflects the severity of the potential impact of a tropical cyclone. The following table shows the different public storm warning signals and what they mean in terms of wind speed and expected damage:

Signal Number Wind Speed Expected Damage

#1 Gale Warning 63-118 km/h Light to moderate damage to trees, power lines, and structures #2 Storm Warning 119-153 km/h Heavy damage to trees, power lines, and structures #3 Typhoon Warning 154-177 km/h Hefty damage to trees, power lines and structures #4 Super Typhoon Warning >178 km/h Hefty damage to trees, power lines, and structures
