Through
cooperative arrangements with South American institutions, the TOGA
program has maintained a network of nine tide stations and four
meteorological stations in Ecuador, Peru and Chile since the mid
1980's. The stations are maintained by NOAA/AOML and the University of
Hawaii. The hourly data are transmitted to down-link stations via the
GOES satellite in real time and processed. The five-day averages
(pentads) at critical stations give us an effective means of monitoring
coastal conditions with good time resolution and compact data volume.

East Pacific SSTs continue to hover around normal values,
while sea levels have taken a decidedly negative plunge in
the last 5 weeks, off central Peru. Sea levels are now as
low as they were during the 2007 La Niña event.
