Yellow Sand Day

Although it sounds like a holiday, it's not.

Yellow Sand - Asian Dust (HwangSa) are fine inhalable sand particles that originate from dry, desert regions of China and Mongolia and blow into other parts of Asia including Japan and Korea.

Yesterday the dust was very noticeable. It looked like a yellow tinted fog covered the sky. When we woke up this morning a fine layer of dust was on our vehicle and on the ground. We were informed that an "Orange" alert status was in effect. This mean't that we could only go outside for short periods of time with any activity. Luckily our training was indoors for most of the morning and by afternoon we returned to normal "Green" levels.

The levels are:

Green : Normal
Amber: Moderate. Consider reducing prolonged and heavy exertion.
Blue "WATCH": Unhealthy. Reduce prolonged and heavy exertion
Orange "ADVISORY": Very Unhealthy. Do not conduct outdoor physical training; Cancel prolonged and heavy exertion outdoor activities
Purple "WARNING": Hazardous. Remain indoors and keep activity levels low
