NPR is reporting that Tropical Storm Moke is expected to cause additional flooding in Hawaii, as the state continues its recovery efforts from last week's hurricane.

In international news, Treasury Secretary Scott Bessent is set to announce a new round of economic pressure on Iran, which President Trump has termed an "economic D-Day." The aim is to compel Iran back into negotiations. Iran's new security chief, Mohsen Rezaei, stated Iran would retaliate in a "seismic manner" and warned that Gulf states implementing the new restrictions could be targeted. NPR's Emily Feng said the U.S. plans to increase pressure on countries doing business with Iran. Longtime U.S. diplomat Alan Eyre expressed skepticism that economic sanctions would alter Iran's regime, suggesting they have instead strengthened hardliners. NPR's Hadeel Al-Shalchi reported that the sanctions could worsen conditions for Iranians already facing high inflation and unaffordable essential medicines.

Separately, Canadian Prime Minister Mark Carney announced Canada will impose retaliatory tariffs on U.S. imports beginning Sept. 8. This action follows the Trump administration's imposition of 50% tariffs on various Canadian goods after trade negotiations between the two countries collapsed. NPR's Scott Horsley said Carney warned that the U.S. is increasingly viewed as an unreliable economic partner and vowed Canada would fight back. Horsley noted that past retaliatory measures, such as China's response to U.S. tariffs, have led to de-escalation.

Domestically, a federal judge has struck down a Trump administration ban on immigrant visas for individuals from 75 countries.
