</pre><pre style="font-variant-ligatures: normal; orphans: 2; widows: 2;" class="">My question is this: Is this expected behaviour from PRMSLmsl, because a few other models such as CMC for example do not include MSLetmsl and only PRMSLmsl and I want to display the lowest central pressures on low pressure systems. </pre><pre style="font-variant-ligatures: normal; orphans: 2; widows: 2;" class=""><br class=""></pre><pre style="font-variant-ligatures: normal; orphans: 2; widows: 2;" class="">Cheers, Mike</pre></div></body></html>
