24. March 15, 200624 The Third Border Initiative (TBI) Disaster preparedness is a high priority for the United States. –Main activities are sponsored by USAID’s Office of U.S. Foreign Disaster Assistance (OFDA), U.S. Southern Command and the Third Border Initiative (TBI) through the U.S. State Department. United States is also exploring options to use TBI funds to expand regional weather forecasting and response capabilities. NOAA’s TBI proposal for upgrading its "hydrometeorological" network (radar, aircraft surveillance, ocean data buoys) is multi-purpose and not just for tsunamis.

25. March 15, 200625 The Third Border Initiative cont’d The NOAA TBI Proposal: –Would also upgrade the telecom network dedicated to sharing information on impending events, including developing a satellite-based natural hazard information network linked to the United States. –In connection with this aspect of the Proposal, NWS in consort with the NOAA International Affairs Office, is preparing a proposed pilot plan to demonstrate the installation of an EMWIN receiving station on a selected Caribbean island and train local meteorological specialists in its use.

26. March 15, 200626 The GOES-10 Move NOAA plans to shift the orbit of a geostationary satellite to improve coverage over South America –Continent will benefit from emerging Global Earth Observation Network –Repositioning planned for October 2006 pending the successful launch of GOES-N, NOAA's new geostationary satellite, and the continued operation of GOES-12. –Shift will help protect lives and property in North, Central and South America by significantly improving satellite detection of natural hazards. –Will further strengthen the WMO's World Weather Watch Global Observing System.
