12.27pm: Trump arrives for FEMA briefing on Dorian. After opening, he says that Dorian 'may get a little piece of a great place: It's called Alabama and Alabama could even be in for at least some very strong winds and something more than that, it could be. This just came up, unfortunately.'So for Alabama just be careful.'

Then Ken Graham, the director of the National Hurricane Center delivers a forecast by video link. When it is over, Trump asks: 'What you think the chances it goes directly straight as the original predictions were?'

Graham says Dorian appeared to be headed north instead of across the Gulf. Trump replies: ' How certain are you it will go north?'

'Every computer model we have is pushing this north,' Graham responds.

Sharpie: On Resolute Desk during briefing

3.45pm: Trump takes questions after an announcement about opioids. He is asked why the map was changed. 'No, I just know that Alabama was in the original forecast'Actually we have a better map than that that's going to be presented....In all cases, Alabama was going to be hit.'

He is asked why the map was altered by sharpie. 'I don't know, I don't know, I don't know. Anything else?' he replies. The White House declines to say who used the sharpie.

6.23pm: Trump tweets a new map, from the South Florida Water Management District on Wednesday August 28. Its spaghetti marks show some forecasts offering some possibility - the chance is not given - that the hurricane could go into Alabama, as well as Mississippi, Louisiana and Tennessee

5.13pm: White House issues a lengthy statement from Trump's Homeland Security and Counterterrorism Advisor, Coast Guard Rear Admiral Peter Brown, saying he gave Trump the forecast on Sunday that Alabama could be hit. He has no meteorological qualifications but did study chemistry at college.

It does not say who altered the map and Rear Adm. Brown is not made available for interviews.

The statement says: 'As the Homeland Security and Counterterrorism Advisor, I briefed President Donald J. Trump multiple times concerning the position, forecast,risks, and Federal Government preparations for and response to Hurricane Dorian.

'I showed the President the official National Hurricane Center forecast, which included the "cone" that projects the potential path of the eye of the storm.

'The President and I also reviewed other products, including multiple meteorological models (often called the "spaghetti models") and graphics that displayed the time of onset and geographical range of tropical storm force winds, storm surge, and rainfall. These products showed possible storm impacts well outside the official forecast cone.

'While speaking to the press on Sunday, September 1, the President addressed Hurricane Dorian and its potential impact on multiple states, including Alabama.

'The president's comments were based on that morning's Hurricane Dorian briefing, which included the possibility of tropical storm force winds in southeastern Alabama.

'In fact, from the evening of Tuesday, August 27, until the morning of Monday, September 2, forecasts from the National Hurricane Center showed the possibility of tropical storm force winds hitting parts of Alabama.

'Additionally, the forecast track changed substantially overt time, such that localities originally concerned about significant impacts, such as Puerto Rico, South Florida, and the Gulf Coast, saw minimal to no impact from Hurricane Dorian.'
