Note

Eventually, some more items will be added, such as Climate and Precipitation data.

Note that a subscription (robot) service to the presently available data is provided, by which the bulletins and/or data are sent by email as soon as they are received and processed. The email subscriptions that are currently available are listed in the Weathermail page.

If you have a particular interest in some data that is not presently shown here, send an email to support@caribeweather.com indicating your interests.

How it is done

It is in that raw form that the official bulletins are distributed, and that is the form in which we retrieve them. But that is not the form in which we present them, as our formatted version of the same document mentioned above illustrates.

To get the formatted version from the raw version, the documents are processed by a text formatting system that we built to process those types of file. The requirements of each type of forecast ``product'' are different, and it was some time before we could get it all correctly. We have tried to reproduce the content of the original files exactly, word for word, giving them only some formatting structure by means of proper indentation, justification of paragraphs, and similar stylistic features. In this way, the documents are more attractive to the eye, easier to read and navigate, and simple to find specific information quickly at a glance.

Technically, the formatting system is a set of filters (shell scripts) based on the standard unix text processing tools sed, awk, perl and nroff. The original raw files are processed by our computer and the processed files are then transfered to the web site, while the original raw files are redistributed by the Weathermail robot system.
