Ok... See what you think

Really? I'm seeing 40 errors. Aside from that, there's a lot of CSS and javascript in the head of your page which should be moved to external files so they can be cached.

Main menu items that open in new tabs/windows are also not good; the visitor should be notified before clicking the link that a new tab/window is going to open.

Overall I find the pages quite hard to read - font size too small and lines too close together. Even though you've broken it up with coloured headings and images/diagrams, I'm just seeing big blocks of grey and it doesn't make me want to read the page (perhaps the fact I have no interest in weather isn't helping). The indented paragraphs are a nice typographic touch, but they shouldn't be used on the first paragraph of a block of content.

Thanks, all the errors on most of the main pages are fixed now. Most were menu items which has recently been updated. I always forget "&amp"; when I include links that have ampersands. I'm going through the remaining pages (50-150 more) to make sure they're compliant also.

I was waiting on moving the CSS out until I was finally satisfied with everything was right. Some pages already have it external (radar pages and certain maps).

Thanks for your critique.

Using MAC and FF when I roll over a link like MAPS and then rollover the submenu it over laps the drop down and can't read the headings anymore

there are times when the header images are changing that the title disappears into the colour of the image

other then that it looks and navigates very nice
