Official Services to Check Rainy Season Heavy Rain Alerts and Disaster Information

During the rainy season, it is more important to know when the rain will intensify and in which areas heavy rain alerts have been issued rather than just whether it is raining. Korea Meteorological Administration's Weather Nuri allows you to check official forecasts, alerts, precipitation radar, and neighborhood forecasts by time all in one place, making it a basic go-to before commuting, going to school, or traveling long distances. Since heavy rain can vary significantly by region, it is recommended to check the hourly precipitation for your current location and destination rather than just looking at national forecasts. Watching the movement of rain clouds on the radar can help you avoid areas where rain suddenly intensifies or decide to delay your plans.

The National Disaster Safety Portal is an official service that organizes necessary actions during the rainy season by situation. It is useful to check the guidelines on what actions to avoid when heavy rain advisories and warnings are issued, and where to move in case of flooding or river overflow risks. If the rainy season extends, not only rain but also compounded risks such as landslides, lightning, strong winds, and power outages may arise, so it is good to read through it with your family in advance. Especially if you live with parents or children, it would be helpful to use it as a reference for arranging evacuation locations, communication methods, and emergency supplies.

The risk of flooding during the rainy season can grow not only with heavy rainfall but also when rain in upstream areas reflects in the river levels. Flood Alert provides information on river levels and flood-related alerts, making it especially useful for people using riverside paths, lowland parking lots, and low-lying roads. It’s important to develop the habit of checking both the river levels and current control situations rather than approaching river areas right after the rain lightens. If you have parked your vehicle in a riverside or lowland parking area, it can also be used as a basis for deciding whether to move in advance when heavy rain is forecasted.

During the rainy season, it is just as important to quickly check on-site controls and evacuation notices as it is to view forecasts in advance. Disaster text messages and Safety Steps App are helpful when you need localized information such as sudden heavy rain alerts, flooding risks, road closures, and evacuation site guidance. It’s good to confirm that emergency disaster text message reception is not turned off on your mobile phone and to check that notifications are functioning properly on your parents' phones as well. The Safety Steps App allows you to view action guidelines and evacuation information by disaster type, making it a good reference even when you are in an unfamiliar area or traveling.

Driving during the rainy season involves more variables than usual. By checking the traffic safety information and related guidance from the Road Traffic Authority, you can revisit basic but often overlooked matters, such as reducing speed on wet roads, securing distance between vehicles, and avoiding flooded roads. In particular, if heavy rain coincides with rush hour, there may be increased danger in underground tunnels, low-lying roads, and construction zones, so it is wise to check local government notices and traffic situations alongside your navigation system. Waterlogged roads can be difficult to gauge in depth and may lead to vehicle breakdowns, so taking detours is the safest choice.

During the rainy season, localized control information can often be more important than national news. Local government disaster safety texts, official SNS, and website notices help you quickly check life-related information such as the closure of specific river paths, underground tunnel controls, requests to move from lowland parking lots, and evacuation center operations. If you use spaces that have a risk of flooding, such as semi-basement or underground parking lots, it is good to follow the government channels of your residence and workplace together. If you are traveling, checking the city or county government notices for the area where you are currently staying will help you get a more accurate understanding of the on-ground situation.
