The disturbed weather over eastern Micronesia is slightly better
organized today and the Joint Typhoon Warning Center has an Invest
Area (97W) centered near 3N158E. ASCAT Analysis indicates a weak
circulation at 2.5N157.5E. Areas of showers associated with this
disturbance continue to develop over Southern Chuuk and Pohnpei
States and parts of Kosrae state. Models differ very much in the
development and track of 97W and further developments are still
uncertain. GFS has been very aggressive with this system and other
models much less so. GFS has consistently shown deeper moisture and
increased winds in the Marianas next week and that is consistent with
our forecast current trends.
