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.

SST and sea level anomalies along the coast continue to
be near-normal and do not reflect the moderate El Niño
conditions (between +0.5 and 1°C) along the equator.
This may be a temporary situation due to normal or above-normal
southeast tradewinds in the eastern Pacific, and
could change quickly if westerly wind events develop near
the dateline, forcing Kelvin waves toward Ecuador.
