Improvements to the Trinidad and Tobago Meteorological Service’s (TTMS) Early Warning System may be coming soon. On Tuesday, the TTMS held its first Stakeholder Consultation, held at the Office of Disaster Preparedness and Management in Tacarigua.
In attendance, both virtually and in person, were officials from the TTMS, ODPM, Ministries of Health, Public Utilities, Tourism, Culture and the Arts, as well as representatives from the Disaster Management Units, media, aviation and marine sectors.
Many stakeholders agreed that the TTMS should capitalise on systems already in place, such as the Public Alert Notification System (PANS) which utilises automated email, WhatsApp, voice calls and Short Message Service (SMS). It was further suggested that a TTMS WhatsApp channel be added to their message dissemination platforms, similar to other Government agencies recently.
The lead time, or the time between the issuance of the alert and the onset of an event, was questioned by many stakeholders. The TTMS representatives collectively indicated that tropical weather is very dynamic and can have lead times less than one hour in some cases. However, with plans of improved and upgraded systems (satellite and radar), the TTMS aims to improve overall lead time when applicable. There are also provisions for the various lead times for events (Alerts, Watches and Warnings), which are not being used unless there is an approaching cyclone. The TTMS indicated that they will revisit the structure of its Early Warning System, taking the lead times into account.
Given our rapidly changing weather conditions, especially during the wet season, many agencies asked for an increase in the frequency of ‘nowcasting’ updates. Nowcasting involves the short-term forecasting of weather, typically within the next few hours.
Also, the issue of persons with disabilities arose, and with the visually-impaired community in mind, voice recordings (audio) was asked to accompany the Alerts. This has been done on few occasions since the implementation of the colour-coded system in 2018.
