Diary of 1949 Typhoon Allyn: Part 4 – The end
Typhoon Allyn was one of the most destructive to pass Guam. Although the eye passes some distance to the South, damage was severe over most of the island. the following is the conclusion of a diary of events during the 10 hours of the storm’s passage over the island.
“1705K: The eye of the typhoon passed approximately 45 miles to the south of the station between 1615 and 1630K. Our pressure has risen two millibars now and should continue to rise as the storm moves on.
“1720K: An item of interest might be that when the air freight terminal went to pieces, there were several cars wrecked. One in particular, a Ford, is folded up just like an accordion and is one complete wreck. Several other cars are almost as bad. The front end of the terminal building here is beginning to sag and the operations sections has a large hole in it. Doesn’t look good if these winds continue as they are.
“1800K: Forecast diminishing winds and eye passage given to radio at 1715K to be relayed to [other bases]. Courier from Harmon arrived 1730K and was given forecast. Wind at this timeis definitely swinging to south presently southeast at 70 knots with gusts to 85 knots.
“1915K: Forecast given … that winds would be 30 knots by [midnight], present winds SE at 50 knots with gusts to 60 knots.
“2200K: The winds are slowly dying down, but still holding steady around 40 knots with gusts in the 50s. Our pressure is on the rise still and by 6 hours everything should be well under control. Light rain is continuing to fall with intermittent heavy showers.”
So in the time span from noon until 10 p.m., the conditions went from showers to dangerous winds back to rain showers. The result was catastrophic. Nearly $20 million (1949 dollars, about $200 million in 2012 dollars) was done to military installations. The economy of Guam was also severely impacted. Most – if not all – of several important crops were destroyed: breadfruits (100% lost), vegetables (90%), banana (75%) and so on.
