Flooding in Jakarta next week?

Hey all! I'm coming to JKT from New Delhi, India for the Linkin Park concert. I'll be staying near Monas and plan to just be in the nearby area. I aim to go to the GBK stadium for the concert. Is there any flooding in this area? I'll get around with Grab/Gojek. Want to know if its all safe.

Also for the concert, is it a fully open air stadium? Ill be on the floor right next to the stage. Should I expect to get drenched and get a raincoat? Heat shouldnt be a problem, I'm from India haha.  
Thanks!
