[talk-ph] Typhoon forecast over Northern Luzon

[Jean-Guilhem Cailton]

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).

Best wishes,

Jean-Guilhem
