Reading a T&T weather warning before you change your plans

A weather screenshot can travel much further than the warning it came from. Before using one to change a journey, appointment or outdoor plan, open the Meteorological Service’s current warning page. This guide explains a checking routine; it does not state whether a warning is active now.

Read beyond the colour

Look for the weather event, issue time, period covered and places mentioned. Read the expected conditions and the action instructions together. A warning applying to one period or location should not be treated as a forecast for every place you may visit.

Use the official explanation

The Met Service’s warning page explains yellow as moderate risk, orange as high risk and red as very high or extreme risk. Green is used for cancellation or discontinuation when risk has reduced. These short labels are only a starting point: follow the full instructions attached to the particular warning and any directions from the authorities.

Keep your plans and updates together

• Save the official page link alongside your appointment or travel details.
• Check again before leaving; an earlier screenshot may have been replaced.
• Ask an event organiser or host to confirm their own arrangements directly.
• When sharing an update, include the source link and its date instead of forwarding a cropped colour badge.
• If you cannot load the latest notice, say that you could not check it rather than assuming that an old notice still applies.
