Due to the predominate wind direction, here on the Big Island, if Hilo were struck, it's very likely that everyone South of the Northerly rift would be safe, unless the winds shift. Those atop and North of the rift would face some problems, more increasingly severe the closer to Hilo. The Observatories, the Saddle and around to the Northern slopes of Mauna Kea would face the brunt of fallout, extending into Waikaloa, Wiamea and into Kona. The North West and mid West side of the island would be the most likely areas to avoid, again, depending on wind directions and obviously Hilo and West thereof.
Evening hours may bring some down slope winds into Puna and evening hours would be the most likely time fallout would appear. The South end of the Island would likely be the safest area of the Island to avoid fallout.
Eta:
This gives Puna residents time to prepare for fallout after a detonation in Hilo. Should the predominate winds prevail during the unthinkable.
Time to seal water catchments, etc.
