A heat wave warning was issued for all of Seoul on Thursday, putting the capital city back under the highest-level heat notice for the first time in 11 days, the state weather agency said.

A heat wave warning is issued when the maximum apparent temperature is expected to remain above 35 degrees Celsius for two or more days or the heat is expected to cause large-scale damage, according to the Korea Meteorological Administration.

The warning took effect for Seoul at 10 a.m.

Previously a heat wave warning was in place over Seoul from July 7-13, when the notice was brought down a notch to an "advisory," which is issued when the maximum apparent temperature is forecast to remain above 33 degrees for at least two consecutive days.

Of the 183 weather zones on land, 126, or 69 percent, are currently under a heat wave warning, while 51 (28 percent) are under a heat wave advisory, the KMA said.

The maximum temperature Thursday is expected to range from 32 degrees to 36 degrees.

On Friday, it is set to range from 31 degrees to 37 degrees; on Saturday, 32 degrees to 38 degrees; and on Sunday, 31 degrees to 37 degrees.
