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.

The negative SST and sea level anomalies along the South
American coast are persisting and becoming more intense.
Intraseasonal modulations are weak and the evolution is
consistent with a strong La Niña event.
