Brisk offshore winds today will continue to direct any released radioactive matter out to sea from sites along the quake-ravaged northeastern coast of Japan.
The favorable winds will blow mostly from the northwest at 15-30 mph throughout northeastern Honshu into Thursday, local time.
This would follow a bout of onshore winds in the lowermost atmosphere on Tuesday and Tuesday night, local time.
Tuesday’s easterly to southeasterly winds wafting along the east-facing coast would imply that any radioactive matter being released at the time by stricken nuclear power plants should have drifted over land normally having a significant population.
Authorities have cleared all residents from a 20-km-radius (or about 12 miles) exclusion area.
