What Are Typhoon Emergency Response Levels? How Do They Differ from Warning Signals?

Warning signals are weather alerts issued by meteorological departments to the public, while emergency responses are levels of defensive actions initiated by the government. Levels range from IV to I, with Level I being the highest.

Two Separate Systems, Each with Its Own Role

When a typhoon approaches, you will hear about two different "levels." They are not the same thing:

Typhoon Warning Signals (Meteorological Departments → Public)

Issued in four colors—Blue, Yellow, Orange, and Red—based on wind strength and duration of impact. These signals are directly linked to school suspensions and work stoppages (see the dedicated article on Typhoon Warning Signals).

Emergency Response Levels (Government → Various Departments)

There are four levels: IV, III, II, and I, with Level I being the highest. These are activated by flood control and typhoon prevention command centers at various government levels. They serve as "mobilization orders" for government departments:

LevelGeneral ScenarioExample Government Actions
Level IVTyphoon may have an impactStrengthened duty rosters, pre-positioning of supplies
Level IIISignificant impactInter-departmental coordination, hazard inspections, recalling vessels to port
Level IISevere impactLeaders take command on-site, evacuation of people from dangerous areas begins
Level IExtremely severe impactFull mobilization, implementation of the "Five Stoppages," large-scale evacuations

How the Public Should Use These Two Signals

  • Use warning signals to decide personal actions: Consider staying indoors when Yellow or higher warnings are issued; strictly stay home during Red warnings.
  • Use emergency response levels to gauge severity: When the government activates Level II or Level I responses, it indicates that officials assess the risk as extremely high. Complying with requirements such as evacuation is essential for your safety.
  • Evacuation orders are mandatory: During emergency responses, if local community officials notify you to evacuate, please comply immediately. A significant proportion of casualties in past typhoons occurred among those who "refused to evacuate" or "returned without authorization after evacuating."

The "Highest Level Prevails" Principle for Response Levels

Provinces, cities, and counties may activate different response levels. Local implementation follows the stricter (higher) requirement. For example, while the province may activate Level III, the city where the typhoon makes landfall might already be at Level I.

Before a typhoon arrives, it is recommended to monitor simultaneously: warning signals from the CMA (China Meteorological Administration) or provincial meteorological bureaus + emergency response announcements from local flood control and typhoon prevention command centers + real-time tracks from TyphoonSays (to judge the typhoon's distance and trend relative to your location). Cross-reference these three information sources.
