Isolated flash flooding continues to be possible across the Southwest... Elevated flows and isolated river flooding in Alaska... Heavy rainfall possible in American Samoa... Flooding possible in South Texas and Florida... .Southwest... Isolated flash flooding is possible through today as monsoonal moisture continues to generate periods of moderate to heavy rainfall. While widespread flooding is not expected, rapid rises on small streams in steep terrain, as well as in arroyos, slot canyons, and normally dry washes, remain possible where heavy rainfall occurs. Debris flows are also possible near recently burned areas. .Alaska... Small stream and river flooding will continue across the western Brooks Range and surrounding areas through this morning. Water levels will gradually improve but remain elevated, with additional rainfall through early next week likely to slow recessions. American Samoa... Heavy rainfall will bring the potential for flash flooding on day 2 (Sun). .South Texas... Tropical moisture may bring the potential for isolated flash, urban and small stream flooding across portions of southern Texas this weekend. Uncertainty still remains in rainfall totals and placement. .Florida... Daily rounds of rainfall may bring localized flash and urban flooding through next week. //TMK $$
