*UPDATED*: It's safe to say Mother Nature isn't providing the kindest of Irish welcomes... Ah well, at least the Queen didn't become air born thanks to her array of wide rimmed hats.
If you're dedicating your day to Obama, the following points of note will be useful.
Airforce 1 is due to land in Dublin at 10.00am. The President and the First Lady will be greeted by President McAleese, who's never been so busy, and the Tainaiste.
Obama will then head off to the US Embassy in Donnybrook (which wasn't without it's up and downs... Bullet proof, bomb proof, tank proof. Shame about the bump in the road. Check out the video here) before spending 45 minutes in Moneygall from 3pm - which is bound to look fierce romantic in the rain (it did, and himself and Michelle enjoyed a pint)
Then he will attend that free concert in College Green. Here's all you need to know about that:
1: Gates open at 2pm and the only point of entrance is at the corner of Dame Street and Parliament Street. The surrounding streets will of course be closed so it's advised to get there earlier than 2pm.
2: No food or beverages will be permitted into College Green, so hopefully you'll be able to queue for a hotdog priced in the region of €4. You can also enjoy carrying around unlidded bottles of water.
3: Signs and banners are also not permitted, but you can bring cameras and camera phones.
4: If you're not enjoying yourself, or really need to wee, you can leave the concert at any time.
5: Those due to speak at the gig include Brendan Gleeson, Gabriel Byrne, Robbie Keane, Brian O'Driscoll and Padraig Harrington.
6: Those playing at the concert include Sharon Shannon, The Coronas, Imelda May, Mundy, and - as previously reported - Jedward.
If you do choose to go, enjoy yourselves and bring a windsheeter. If you don't - there's coverage on RTE1 from 9.20pm to 11.30pm, from 3.00pm 'til 6pm, while TV3 are showing coverage all day.
