Diary of 1949 Typhoon Allyn: Part 2 – Conditions worsen

If you missed it, read the introduction to this article and part 1.

What is rawin? What is the hydrogen shack? What is Antrac? What is a T-6? Well, I’m learning as I transcribe this, too. I’ve provided links to other sites that provide more information, but some things are still a mystery to me. For instance, Antrac appears to be related to air traffic control (that is, what I’ve learned from web searching). But I could be wrong.

The following is an hour of notes from Typhoon Allyn.

“1437K: Just went outside to check on the T-6’s at the east end of the ramp. They are not in sight. Don’t know whether they have been moved or whether they are out of sight on the low end of the ramp. It is very difficult to stand erect in the open. Andersen AFB is estimating 85 knots. No buildings have blown down but trees are starting to go over. The pole for the Antrac antenna is swaying about six feet at the top. One pole has gone down at the Rawin shack. The banana trees have been uprooted. Rawin reports that the T-6’s were still on the ramp the last time they went by.

“1445K: The corrugated roof on the inflight kitchen quonset is starting to tear off. One section is gone completely and another is starting to rip off. Estimate that the Antrac pole will stay up another hour or hour and a half.

“1455K: Capt. Myers just returned from quarters area, he said that the large hangar doors just went through th PLM hangar as he came by. Heavy rain just began to fall and the visibility has been reduced to less than one eighth of a mile and the wind is now hanging at about ninety knots. The rain is in sheets and horizontal with the ramp. Debris is beginning to fly and the inflight kitchen is still holding its own. The wind tee is just about demolished.

“1510K: The station is being used as a fire control center for this area. The fire marshall has men stationed and is standing by himself for fires that are reprted into this station. The observer will not be able to take psychrometer readings much longer as it is impossible to stand against the wind.

“1515K: Numerous power lines have blown down, and island power is due to go off at anytime. We can’t get the emergency power unit to work.

“1520K: The lights just went out. No emergency power as yet, but repair crews on the way. Estimating the winds at 80 knots and the visibility at three eighths of a mile in torrential rains.

“1530: Pressure is dropping on an average of four millibars per hour and the tendency is still down. The bottom is really falling out of this. Sheet metal is now tearing off of the depot hangars and the Rawin shack is OK; however, the hydrogen shack is going. The doors have been blown off and it shouldn’t last much longer. Debris is traveling along the ramp at about twenty miles per hour.
