Tropical Depression Moke Discussion Number  17

Moke continues to be in a disorganized state, with only sporadic 
bursts of convection in the northern semicircle.  A recent OSCAT 
pass showed maximum winds of about 30 kt in a small area on the 
northern side of the circulation, so the initial intensity will 
remain 30 kt on this advisory.  The scatterometer pass also showed 
that the circulation was losing definition and becoming somewhat 
elongated.  Given this structure and the persistent shear plus 
dry environment, Moke is not likely to hold onto tropical-cyclone 
status for much longer.  Thus the new forecast shows that Moke will 
dissipate later today, which is consistent with the latest model 
guidance.  

The depression continues moving slightly north of due west at about 
12 kt.  A strong low- to mid-level ridge should hold firm north of 
Moke until the cyclone dissipates.  The new forecast is similar to 
the last forecast and is on the southern side of the guidance.   
Even though Moke is well south of the Hawaiian Islands, periods of 
heavy rain causing flash flooding are possible across portions of 
the Big Island today.
 
Key Messages:
 
1. Rain bands associated with Tropical Depression Moke will continue 
over the Hawaiian Islands through Monday. This rainfall may produce 
areas of flash flooding for the windward and southeast Big Island, 
especially in steep terrain and over areas that were affected 
recently by Lala. Flood prone and low lying locations, as well as 
urban areas, may also see instances of flash flooding.
