27 May - 10 June: I need to do some server upgrades, so there will be intermittent downtime during this period. I'll do my best to only work on things when we are in Slight Risk or lower.

Latest changes:
(1) 27 May: The radar and satellite images are now created with Gempak 7.4, but I can't get the surface maps to work. They'll remain on Gempak 5.7 for now.
(1) 25 May: Locally-produced radar images are back online, but I need to tweak this new color table a little more. DHR is a little noisier than N0R, too. I'll leave one backup option running for now, just in case.
(2) 2 May: The Gempak products that used RAP output kept crashing, so I have temporarily disabled them.
(3) An "https" option is now available: change your links please!
(4) Occasional slowness may happen when I'm processing data for other projects. Sorry about that.
