Thank you in advance.

OA: Coffee prices rose sharply Monday after a weekend cold snap in Brazil raised concern that the world's largest crop could be damaged at a time when supplies are already tight.
Here, the modifier in blue implies that MONDAY was less than a week ago.
Thus, the portion in red refers to the PRESENT -- just a few days after this past Monday.
The usage of are (present tense) conveys that RIGHT NOW -- just a few days after prices rose this past Monday -- supplies ARE tight.
