Flash floods can disrupt roads and highways within hours, as seen during the recent flooding around Shah Alam and surrounding areas.
But if you're planning to drive during heavy rain, how can you check whether your route is affected by flooding or road closures?
Fortunately, Malaysia has several official platforms that provide flood warnings, rainfall information, weather alerts and traffic advisories. Here's where to check before starting your journey.
Always verify reported road closures with the relevant authorities. Flood and weather alerts do not guarantee road conditions.
How To Check Flooded Roads And Road Closures In Malaysia
No single platform monitors every flooded road nationwide. However, combining information from several official sources can help motorists identify potential risks and reported closures.
Start with the resource that matches the information you need:
01 / FLOOD WARNINGS & WATER LEVELS
Check river levels, rainfall observations and flood warning statuses.
Here's how each resource can help you plan your journey.
1. Public InfoBanjir: Check Flood Warnings And Water Levels
Public InfoBanjir's water-level monitoring data for Selangor as of the morning of 4 November 2026 shows several stations exceeding their alert, warning and danger thresholds, including Saujana Aman and Taman Desa Kemuning.
Operated by the Department of Irrigation and Drainage (JPS), Public InfoBanjir provides rainfall observations, river water levels and flood warning information across Malaysia.
Find monitoring stations near your planned route or destination.
Review the latest readings, warning status and observation time.
Pay attention to stations displaying Waspada (Alert), Amaran (Warning) or Bahaya (Danger), particularly when water levels are rising.
IMPORTANT:
A flood warning or high river level does not automatically mean a nearby road is closed. Use this information to assess flood risk, not to confirm road passability.
2. MetMalaysia: Check Heavy Rain And Thunderstorm Warnings
Before travelling, check MetMalaysia for the latest weather forecasts and warnings, particularly those involving thunderstorms and continuous heavy rain.
You can also use the department's myCuaca mobile application for convenient access to weather information.
Focus on warnings affecting your starting point, destination and areas along your journey, rather than checking only the weather at home.
3. PLUS Malaysia: Check Highway Closures And Traffic Updates
If your journey involves PLUS-operated highways, check PLUS Malaysia for the latest traffic advisories, reported closures, diversions and reopening notices.
The PLUS App also provides highway traffic information and access to traffic cameras, helping motorists assess conditions at covered locations.
During flooding, pay particular attention to the location, travel direction and timestamp of each advisory. Conditions may change rapidly, and an earlier closure notice may no longer reflect the current situation.
The recent flooding along the NKVE near Shah Alam demonstrates why checking official highway announcements matters, even when a navigation app suggests an alternative route.
4. JKR And NADMA: Check Other Road Disruptions
Flooding can also affect federal and state roads beyond major expressways. The Public Works Department (JKR) monitors disaster-related road incidents, including flooding, landslides and damaged infrastructure, through its disaster management operations.
Meanwhile, the NADMA Disaster Portal provides broader disaster information and references to relevant government agencies.
These sources can complement highway advisories when planning journeys outside PLUS-operated routes. However, the availability and timeliness of road-specific updates may vary.
5. Shah Alam i-Lensa: Local CCTV And Flood Monitoring
For motorists travelling around Shah Alam, the Shah Alam City Council (MBSA) has developed i-Lensa, a CCTV-assisted monitoring and early-warning system.
According to a Media Selangor report, the system supports monitoring of selected locations across the city, including areas associated with flood risks.
Such systems can help authorities monitor developing conditions and support flood-related warnings.
However, motorists should not assume that every CCTV feed is publicly accessible or that all roads are covered. Public viewing access should be confirmed through MBSA's official channels.
BEFORE YOU DRIVE: 3 QUICK CHECKS
01. CHECK THE WEATHER
Look for active MetMalaysia warnings affecting your planned journey.
02. CHECK FLOOD CONDITIONS
Use Public InfoBanjir to review nearby water-level and rainfall monitoring stations.
03. VERIFY ROAD CONDITIONS
Check official highway or road-authority advisories for reported closures and diversions.
A CLEAR MAP DOESN'T ALWAYS MEAN A SAFE ROAD
Google Maps and Waze may help identify congestion and alternative routes, but they cannot guarantee that a road is safe during flooding. Never drive through floodwater, even if other vehicles appear to be crossing.
Frequently Asked Questions
How can I check flooded roads in Malaysia?
Start with Public InfoBanjir for flood conditions, then check the relevant highway operator or road authority for reported closures. No single platform confirms every road's condition nationwide.
Can I trust Google Maps or Waze during floods?
Both are useful for navigation and traffic information, but a suggested route does not guarantee that a road is safe or free from floodwater. Cross-check official advisories and never attempt to drive through flooded sections.
Where can I check live flood CCTV in Malaysia?
Some highway operators and local authorities offer CCTV monitoring. The PLUS App provides access to selected highway cameras, while Shah Alam's MBSA i-Lensa supports local monitoring. Public availability, camera coverage and update frequency differ by system.
The bottom line: Before driving during heavy rain, check weather warnings, flood conditions and official road advisories together.
These resources can help you make a more informed decision, but they cannot guarantee that every road is safe. If conditions are uncertain, delaying your journey may be the safer option.
