Subject: Enforce TLS 1.2 or Higher on Several NWS Websites
Effective date: July 27, 2020

Effective on or about July 27, 2020, beginning at 1400 Coordinated Universal Time (UTC), the National Centers for Environmental Prediction (NCEP) Central Operations (NCO) will enforce Transport Layer Security (TLS) 1.2 or higher connections to the websites listed below.
The following websites will be affected:

Where “*” also includes “www.”
Any browsers or services that do not support TLS 1.2 or greater and access these sites will need to begin support of TLS 1.2 or greater in order to avoid service interruption.

The Saratoga PHP scripts that use NWS data all use PHP's built-in cURL or stream access to obtain data from NWS sites,
so your website's PHP/cURL version should be up-to-date to have the scripts continue to operate.

To make sure your website is TLS1.2 capable, create a page with
Code: [Select]
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "">
<html xmlns="">
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>PHP Info</title>
<?php phpinfo(); ?>
on it, display the page in your browser and look for
Registered Stream Socket Transports   tcp, udp, unix, udg, ssl, sslv3, tls, tlsv1.0, tlsv1.1, tlsv1.2

If you don't see the tlsv1.2 upgrade your PHP to V7+ or contact your webhoster to have PHP updated.
