According to the local news this morning, the meteorological service is hoping that the winds will shift by this afternoon (Thursday). In my barrio, although Wednesday started with clear blue skies, by early evening there was chocking acrid smoke to the level that buildings a few blocks away were obscured. By nightfall you could see the smoke in the headlights of autos on the street.

It's still as bad this morning, having permeated the air inside as well. People are reporting asthmatic and allergic reactions. It's not helped by the low humidity (currently about 35% RH).

The fires in the delta (north of BsAs) have been burning out of control for several days now, but the situation has been much worse (as far as air quality in BsAs) in the last 18 hrs. Routes to the north of the city have been closed due to hazardous driving conditions (fog + smoke), and there have been a number of auto accidents with fatalities over the past couple of days.
