Tropical Depression 26W continues to gain strength

at 220600z, tropical depression 26w (twentysix) was
located near 7.5n 148.5e, approximately 410 nm southeast of Guam,
and had tracked north-northwestward at 09 knots over the past six
hours. Maximum sustained surface winds were estimated at 30 knots
gusting to 40 knots. See ref a (wtpn31 pgtw 220900) for further
