An upper-level low to the east and a monsoon trough to the south continues to approach the Marianas and the two systems are expected to combine throughout the week to create substantial rainfall for the islands.
According to the CNMI Homeland Security and Emergency Management Agency, the two systems are on track to get the Marianas’ wet season started.
An upper-level low is a closed circulating eddy while a monsoon trough is described to be wind surges accompanied by bursts of thunderstorms.
The combined systems are expected to drop three to six inches of rainfall throughout the week. Showers started to pick up as early as Sunday evening.
Localized flooding will be possible in low-lying and poor drainage areas. Check storm drains in your area to make sure they are not clogged and, if planning anything outdoors, have a backup plan in place in case of rainfall.
According to an update from the National Weather Service in Tiyan, Guam, showers are expected to continue throughout the week and next week.
Rainfall has been very low over the Commonwealth since January and rainfall will likely be below normal through July.
For Saipan specifically, the drawdown of fresh water resources will still be a problem during the next few weeks and fire danger will still be extreme over parts of the Northern Mariana Islands.
