What is a SAT?

SAT is an Early Alert System (from its spanish translation, Sistema de Alerta Temprana) which has as its primary objective to give support to the community by diffusing the relevant hydrometeorological information, before possible threats. This objective looks to enhance the preparation, relieve and reduce the impact of natural disasters in the most vulnerables populations in the region.

Fundamentals

What does SATs consists of?

Disciplinary Equipment

SAT System Operation

  1. The Meteorological Surveillance Personel observes the bad weather formation, and its evolution is monitored. Permanent communication with the COE from SINAPROC
  2. The meteorological and hydrological analysis personel follow the registry from the telemetric stations.
  3. A special probability forecast for floods. Destiny: SINAPROC
  4. The SINAPROC alert protocol is activated. The meteorological and hydrological surveillance continues.
  5. The Emergency Operation Center from SINAPROC acts
  6. Preparation of reports an lessons learned. Sat bettering.

Basic Equation for the SAT's Hydrological Viability

Tc > Ta = t1 + t2 + t3

Tc = basin concentration time
Ta = total time required to give the alert
t1 = time to register and broadcast data
t2 = time to evaluate and calculate
t3 = required reaction time
