Heavy Rain Update and Tropics Update - Friday September 2nd, 2022

Overview:

WHAT: MARGINAL RISK to SLIGHT RISK of Heavy Rain

WHEN: Mainly late morning through early evening. Outlooks are for the next 3 days, but additional outlooks are possible early next week.

WHERE:  The entire area.

CONFIDENCE:  We are confident that there will be thunderstorms across the area and low-moderate confidence in heavy rainfall somewhere across portions of the forecast area over the next few days. Exactly where this occurs has a lower confidence level. Heavily urbanized and other flood-prone areas may experience flooding, especially if multiple storms impact the same location(s).

Impacts:

  • Rainfall rates up to 3 to 4 inches per hour could cause flooding of low-lying and poorly drained areas.

  • Possible ponding of water in low-lying areas and some potential for localized flash flooding

Tropics Update:

  • The tropics are becoming more active, but no local impacts are expected.
  • Tropical Storm Danielle is forecast to become a hurricane today but is expected to remain over the northern Atlantic waters and is not expected to pose any threat to land. 
  • Currently, most guidance suggests that the system east of the Leeward Islands will remain at sea. However, it is still further out and models do struggle with forecasts before there is a defined center to lock on to. For that reason, the system should continue to be monitored and we will certainly send an update if the threat to the local area looks to be increasing.
