Hi, - "Potentially catastrophic Super Typhoon Megi approaching the Philippines" http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=1661 - From http://www.pagasa.dost.gov.ph/: Hourly Update on Typhoon "JUAN" As of 6:00 a.m., today (Monday, 18 October 2010), Typhoon "JUAN" was located at 190 km East of Tuguegarao,Cagayan. (17.5°N, 123.5°E) with maximum sustained winds of 225 kph near the center and gustiness of up to 260 kph. Moving West Southwest at 19 kph. Estimated central pressure: 922 hpa. - NOAA numerical weather model, as shown by zyGrib, forecast that typhoon trajectory should sweep over Northern Luzon. Certainly, Mappers from the Philippines could say better what could be of help. It seems that OSM map of the potentially affected area contains many towns without connecting roads (http://osm.org/go/42hNR6-- ). It is difficult to trace them without more imagery than is available now (I've let our contact at Spot Image know about this), but we could already use Landsat to map rivers (as heavy rains are forecast, and flash floods possible).
