I've not seen this before, but I'm pretty sure the Fallout 3.esm should be loaded before the Anchorage.esm. I'm assuming you are using the Fallout Mod Manager, so check the box for the Fallout 3.esm while your at it. ESMs should be grouped at the beginning of your load order; you have the Enhanced Weather and Dynamic Weather ESMs down in your ESPs section. Given how few mods you are using, a merged patch may not strictly be required, but I have to recommend it anyway. Once your load order is solid, it takes just a few minutes tops to generate a merged patch. Load up the mods you use in FO3Edit. Right-click one of them in the tree in the left pane. Select "Create Merged Patch". Give it a file name of your choosing, when it asks. Your merged patch will appear at the bottom of your load order in the tree. Close FO3Edit; make sure you save the changes to the patch you created, when it asks. Mark your merged patch to be loaded last in your order. That's all. That said, have you already ruled out performance- or machine-related crashes? I was getting occasional crashes when using Enhanced Weather, what I figured were performance-related crashes. My machine is pretty out-dated at this point. However, someone else in a recent thread here said he/she was getting crashes specifically from the 'Weather Sounds in Interiors' plugin for Enhanced Weather. Unfortunately, I never tried removing that plugin, so I don't know if that would have helped me. If the minor tweaks to your load order and creation of a merged patch don't alleviate your crashes, you might try removing that plugin. Okay I will try what you have said but I read that all weather mods should be loaded last after FWE and other mods as it causes issues so I don't know if I should move the .esms up to the top of the list?
