Two B.I.G. Booths Stand Firm in
220 MPH Super Typhoon
December
17, 1997: Super Typhoon Paka moved
through Guam and the Marshall Islands
during mid-December of 1997.
A typhoon watch was issued by the NWSFO,
Guam, at 2300 UTC 14 December for the
Marshall Islands when Paka was over 1200
km (650 nm) east-southeast of Guam. The
watch was upgraded to a typhoon warning
for Guam, Rota, Tinian, and Saipan at
1530 UTC 15 December [at the same time
that Paka was upgraded to a super
typhoon with sustained winds of 72 m s-1
(140 kt)]. During its closest approach
to Guam, the typhoon intensified to 220
mph.
Despite the loss of all official wind
recording equipment on the northern
portion of Guam (one amateur wind record
was available throughout the event),
wind fields were produced for Super
Typhoon Paka's passage over the island.
This was made possible by the use of
GBVTD to produce wind fields based on
the Guam WSR-88D Level IV VD's prior to
the loss of power at the radar.
The duration of typhoon force winds was
greater than 8 h across some populated
regions (> 7 h over most of the northern
two-thirds of the island). This long
period of strong winds and the wind
direction shifts (> 180o) that occurred
as the typhoon's eyewall moved over the
island likely contributed to much of the
observed damage.
Two B.I.G. steel booths stood in the
pathway of Super Typhoon Paka. Though
wooden structures around the booths were
flattened, the booths, including their
glass windows, were intact after the 220
mph winds passed over.
