Now, as Isaac moves north from Louisiana, it could affect other parts of the country, and we'll be following that story as it develops.
The other big story we have been following this week is the Republican National Convention in Tampa, Florida. Today is the final day, and it's an important one for GOP presidential nominee Mitt Romney. He'll officially accept the nomination this evening. Yesterday, Romney took a break from the hubbub of the convention to do a little campaigning elsewhere. NPR's Ari Shapiro reports on his getaway.

It is the wind that defines the strength of a hurricane. The storm is not a hurricane at all until the wind reaches 74 miles per hour. Hurricane Isaac's sustained winds were not much beyond that, so it was a Category 1 storm, not two, three, four or five. But if the winds define a hurricane, it's the water that can do the most damage.
Just to keep us up to date here on Hurricane Isaac, it's become a tropical storm and forecasters expect to downgrade it to a tropical depression by this evening. That is small comfort, though, to people facing the storm's strong winds and heavy rains. States as far north as Ohio could feel Isaac's effects.
But now to Tampa, where this evening Mitt Romney will formally accept his party's nomination for president.
Last night, though, the stage belonged to vice presidential nominee Paul Ryan. In a campaign, it often falls to the running mate to be the attack dog and Ryan sounded up for the job. It was also a chance for the rising GOP star to defend his own ideas.
Let's follow up on another story. Earlier this year, five big banks settled the so-called robo-signing case, admitting they rushed the foreclosure processes for thousands of homeowners. Now, those banks are working to forgive and modify $20 billion worth of home loans.
As NPR's Yuki Noguchi reports, yesterday was the first chance to look at how banks are handling this part of the settlement.
YUKI NOGUCHI, BYLINE: Joseph Smith's first full report wasn't due until November, but he was eager to keep the issue top of mind.
We're getting a reminder here of how fiercely competitive this race is. Even as his party's convention is going on, Mitt Romney, campaigning in Indiana and President Obama, of course, not taking the week off - as rival candidates sometimes do during the opponent's convention. He's been making his case the last couple of days in college towns, trying to energize young voters.
And NPR's Scott Horsley is on the road with the president.
Turkey's foreign minister is in New York today. He's urging the United Nations to begin sheltering and protecting refugees inside Syria. It's a move that would almost certainly require international military involvement to safeguard an area inside the country. But Syrian President Bashar al-Assad says talk of a safe zone inside his country is not practical. NPR's Peter Kenyon has this report from Istanbul.
