Did Mount St. Helens erupt with little warning?
The eruption of Mt. St. Helens on May 18, 1980 did give significant warning before the actual large eruption took place. There was a period of a month and a half of unrest before the flank collapse and lateral blast events took place. The unrest began being documented March 15, 1980, however it was not immediately recognized as possibly being a precursor to a volcanic event. The seismic events were first recognized as precursor activity on March 20th, 1980 with a magnitude 4.2 under the north flank of the volcano (Which also turned out to be the eruptive and failure point of the volcano on May 18). For further and detailed readings on the precursor events before the triggered eruption please see related links for the Cascade Volcanoes Observatory.

Why would porcupines gave warning signs to their predators?
Porcupines have evolved to give warning signs to potential predators as a survival strategy. When threatened, they may emit warning vocalizations, display their quills, or engage in defensive postures to deter attackers. This behavior serves to communicate their unpalatability and physical defenses, allowing them to avoid confrontations and conserve energy. By signaling their readiness to defend themselves, porcupines can reduce the likelihood of predation.
