phwxenthusiast wrote:the lowest pressure reading i found in the Bicol Region was in Libon, Albay the eye tracked right over this town (15mi northwest of the landfall point). it recorded a min pressure of 960hPa. surrounding weather stations all recorded in the 965-975hPa range. Wind gust from Tabaco, Albay was 185kph (100kt)--and Tabaco is at the right half of the eye (motion-relative). and again, Legazpi with the 962hPa as the eye moved on top.

these station data are from Project NOAH and were giving updates every 15 minutes--even if they did miss the lowest readings, i don't think it would be far from what they actually recorded.

also, i believe these instruments were donated by Japan so I don't doubt their quality. sure, some of them may not have been calibrated properly. however, since all the stations that the eye tracked over reported nearly similar readings (from the environmental MSLP all the way to the minimum pressure), I'm more likely inclined to think that the 960hPa-range readings are reflective of what the actual pressure was.

my guess for landfall is 958hPa and a 95kt 1-min sustained max wind.



DOST ASTI sensor installed at the roof deck of the 2 storey Rapu-Rapu Municipal Hall recorded a minimum station pressure of 953.5 hPa (or approximately 955 hPa MSLP) at 2014-07-15 16:45:30 PST during Rammasun's eye passage. The municipal hall is located just 3 masl.
